It’s been over 3 years since I cancelled the app and they refused to cancel the subscription and are still charging me. I have emailed, no luck. This is fraud. I will report to my bank now

They’re a bunch of thieves! After paying for a month of the nutrition plan on their website (April), I canceled the weight-loss program on CertifiedFasting.com directly through my account. I noticed that starting in May, they have been attempting every month to automatically charge my Revolut card 36 euros to renew the weight-loss program, even though I canceled it and did not authorize continued payments.

We also want to clarify that recurring charges cannot continue without an active subscription linked to the account. Any renewal is associated with the subscription selected during registration and the payment authorization provided at that time. If there is any discrepancy regarding the subscription status or billing history, we would like the opportunity to investigate it thoroughly.

This has to be the worst, most predatory site I have ever seen. It is almost impossible to figure out how to cancel your subscription. They make you go through so many steps and every chance they get, they guilt you, essentially mocking you for not wanting to continue paying an insane amount for no value. All their options for cancelling say things like "No, I don't care about my health and don't want to lose weight" just to guilt you into not cancelling their garbage service.
No one checks or responds to their help/contact info no matter what your message is or how you choose to contact them. That way they can avoid any accountability for their disgusting tactics.

Do not use this app or this company!! It is a scam, content is all AI generating and is deceptive. Multiple charges a month, no email reminders or content and the interface is terrible. Seriously, save yourself some time and hassle and find a credible company.

ABSOLUTE SCAM!!! They have tried charging my card every month for almost 6 months now even after confirming cancellation months prior. The website is horrible and useless (glorified timer). They get people to pay and try charging their card without them even knowing. AVOID!!

I signed up for a €16 promotional plan. They emailed me a link to complete the plan, but they charged me another €30 without my knowledge. I activated the "Shopping List" for €19.00, but it doesn't work. It's a complete scam. I filed a complaint because I'm also receiving emails to activate the plan. The service is highly unprofessional and fraudulent. I've asked for a refund, but they remain vague and unresponsive to the evidence I've sent to support the claims made above. Avoid wasting money.

Does anyone know how I can take legal action against this company?
I cancelled this service because it did not seem genuine, but they have continued trying to take money from my account. I cancelled in May 2025, and since then, every three months they attempt to charge me again.
I blocked the first account they used, then they tried another one, which I also blocked, and now they are trying again. I have screenshots from my bank showing all the attempts and reports I made.
Where can I report them, and what legal steps can I take? I would really appreciate your help.
Here is my email: petersamir1994 @ gmail.com
Do you want me to upload all your bank accounts that you use to take the money ?

I wish to read reviews first. It's impossible to cancel subscription, it's very hard to reimburse money. These are definitely scammers and I wish all of us could claim their activities in the social nets.
I want to formally express my dissatisfaction with your intermittent fasting program and the generalized approach this company applies to all clients.
Their service promotes a one-size-fits-all model that fails to take into account the fundamental differences in individuals’ health conditions. At no point during onboarding are clients asked about critical health indicators such as hemoglobin levels or the status of essential micronutrients. There is no recommendation to undergo basic medical tests before starting a fasting regimen, which is concerning. Such assessments are essential to determine whether a person can safely follow the proposed schedule.
Furthermore, the meal plans and recipes provided do not reflect individual nutritional needs. There is no consideration of potential deficiencies in vitamins such as D or E, or minerals like iron, potassium, or calcium. For example, conditions such as anemia can only be reliably identified through blood tests, yet your program ignores this entirely. The recipes do not clarify whether they address or compensate for such deficiencies.
As a result of this lack of personalization and medical awareness, users may experience serious negative effects. In my case, I was unable to complete even a full month of the program due to extreme fatigue and a general sense of weakness and inability to function properly.
It is evident that the primary focus of this company is to sell as many subscriptions as possible, rather than to provide a responsible and individualized service. This approach assumes that all people are the same and can follow identical plans, which is not only inaccurate but potentially harmful.

Hello Юлия,
Thank you for taking the time to share such detailed feedback, we’re sorry to hear about your experience and the concerns you’ve raised.
We’d like to clarify a few important points regarding how our program works. Our fasting plans are not intended to be a one-size-fits-all solution. After registration, customers are guided through a series of questions related to their lifestyle and health. Based on these responses, the system determines whether the program is suitable. If anything potentially concerning is identified, customers are advised to consult with our support team or a specialist before proceeding. In cases where fasting is not recommended, the system restricts access and directs customers to contact support for further assistance.
Additionally, customers are always welcome to share more detailed health information at any time. This information can be reviewed by our nutrition specialists, who can provide further guidance, including adjustments to calorie intake or general recommendations where appropriate.
We also want to emphasize that our program is designed as general wellness guidance and does not replace medical advice or clinical testing. We always encourage users to consult with a healthcare professional before starting any dietary or fasting routine, especially if they have pre-existing conditions or concerns.
Regarding your comments about cancellation and refunds, cancellation is available through account settings, and we’re always ready to assist if anything is unclear or not working as expected.
Our Customer Experience team has now contacted you directly to review your case and help resolve the situation. Please check your email (including your spam folder) for our message.
We want to make sure everything is handled correctly for you and are here to help.

Very very bad customer service!!! I wanted to cancel subscription and the site is so misleading, you have to jump through multiple loops to finally find what you need and cancel!
Also, even though I cancelled the day before, I was still charged because apparently cancellation needs to be done 48 hrs before!! And of course nobody tells it to you upfront!
They also charge you early because they operate on European time, not on US time.
Anyway, awful experience and very frustrating!!!

Hello Anna,
Thank you for sharing your experience, we’re really sorry to hear how frustrating this has been for you.
We understand your concerns regarding the cancellation process. While cancellation is always available through the account settings, it should be straightforward to complete. We appreciate your feedback about the navigation, as this helps us identify where improvements may be needed.
Regarding the 48-hour notice, this is part of our subscription terms and is outlined during signup as well as in our Help Center and Terms of Service. It means that cancellations need to be made at least 48 hours before the next billing date to prevent renewal. Billing times may also follow our system’s standard processing time, which can differ depending on time zones.
We can see that you’ve already been in contact with our support team, and detailed information has been provided regarding your case. If anything remains unclear or if you have additional questions, we’re here to help and would be happy to review everything further with you.
Thank you again for your feedback, it’s important to us.

Dear Sir or Madam,
I am writing on behalf of my mother, regarding unauthorized charges associated with your service.
She accessed your website approximately two months ago but did not subscribe to any paid plan, nor did she provide explicit consent for any recurring payment. Despite this, she has been charged twice.
Following the first charge in February, she contacted your customer support and received confirmation that any subscription had been cancelled. Nevertheless, a second charge was processed yesterday.
This situation raises serious concerns regarding compliance with EU law, in particular:
Article 6 and 7 GDPR – lack of valid consent for processing and billing
Article 7(3) GDPR – failure to respect withdrawal of consent
Article 5 GDPR – lack of lawful and transparent processing
Directive 2011/83/EU – absence of clear and explicit consent to payment
In light of the above, I formally request:
Immediate cancellation of any active subscription
Full refund of all charges
Written confirmation that all personal data has been deleted in accordance with Article 17 GDPR
Please treat this matter with urgency. If I do not receive a satisfactory response within 24 hours, I will escalate this issue to the relevant data protection authority and pursue legal action.

Hello Andrei,
Thank you for bringing this matter to our attention. We understand how concerning unexpected charges can be, especially in a situation like the one you’ve described on behalf of your mother.
We would like to clarify that charges can only be processed after a plan is selected and payment details are provided during registration. That said, what you’ve described does not sound right, and it’s important for us to review the case in detail to understand exactly what happened, including the previous cancellation request and the recent charge.
Please ask your mother to contact our support team directly at [email protected] and mention that she was referred from Trustpilot. This will allow us to locate her account securely, review the billing history, and address all aspects of her request, including subscription status and data-related concerns.
We take such matters seriously and will ensure her case is carefully reviewed and handled appropriately.

I had a very bad experience with CertifiedFasting.
I selected a reduced 5-day option, but afterwards I was charged multiple times without any clear confirmation or consent. The money was withdrawn directly from my card, and this happened repeatedly.
I canceled my subscription immediately, removed my account, and requested deletion of my card details. Despite this, I continued to receive emails and was informed that multiple subscriptions were still active.
This is not transparent and not acceptable.
Due to these practices, I have:
reported the case to ANPC (Romanian Consumer Protection Authority)
filed complaints with Latvian authorities (Consumer Rights Protection Centre – www ptac.gov.lv)
initiated steps with my bank for chargeback
I strongly believe this is not an isolated case, as many similar complaints are publicly available.
I advise anyone in a similar situation to:
contact their bank immediately and request a chargeback
file a complaint with their local consumer protection authority
report the company to Latvian authorities here: www ptac.gov.lv
I expect a full refund and confirmation that all my data and subscriptions are permanently deleted.
For transparency, this service is operated by:
Company: Nutrameg SIA
Registration number: 50203370651
Address: Lastadijas iela 6, Riga, LV-1050, Latvia
The company is responsible for subscription services provided via CertifiedFasting and similar platforms.

Each time I clicked on an option in your application, money was withdrawn from my card. This happened three times, and I have lost a significant amount of money.
I was asked only once which subscription I wanted. I selected the reduced 5-day option, but afterwards I was charged much more through the application without any additional confirmation.
I would like to request a refund for these charges.
Also, I cannot find where to delete my card details from your website. Please remove my card information from your system or guide me on how to delete it immediately! I canceled my subscription imediately and based on all your reviews here, and If this issue is not resolved promptly, I will be forced to escalate the matter through my bank and the relevant consumer protection authorities, and pursue legal action if necessary.
