I bought subscription for one month and confirmed payment of 389,- CZK, in next 15 minutes they steal from my card next 2x499,- CZK. The support on their app chat will never reply to you as well as by email. Already reported to my bank and police

They ask for the payment, get the money and didn t provide anything.
If you ask for reimbursment or for the plan/program your acount is closed and an AI will tell you many times, why you can't get the money back.
Don't subscribe!!!

I subscribed to a one-month trial plan for €16.
On the very same day the subscription was finalized, CertifiedFasting attempted to charge my card three times—through Dietcf.com and Fasting, SIA—for a Premium subscription without any authorization from me, to the extent that my bank froze my credit card.
At the end of the trial period, again without my authorization, CertifiedFasting attempted to charge me the amount due for an automatic renewal, even though I had never subscribed to any renewal.
Once again, my bank froze my card.
I therefore completely blocked all transactions with this so-called “merchant” and formally informed them of my deep dissatisfaction with their practices. I have also completely stopped any interaction with them.
I strongly advise against using their services.

we’re sorry to read about your experience. To clarify, subscription terms, including renewals, are shown during sign-up and must be accepted before completion. However, no charges should be appearing for services you haven't ordered. We’d really like another chance to review your account to understand what went wrong and resolve this situation as best as possible.

If i could negatively review this company i would. i signed up for a service that was not what i was expecting and contacted their customer service within the hour. they promised they would not charge me and close the account. the charge stayed in my Paypal pending for two weeks then they put it through. interestingly enough their policy for refund is after 14 days. they refused to comply with a refund and their original promise to 'not charge' me for my mistake. now they have thrown a measly 30% refund my way for a product i never even looked at or used. DO NOT DO BUSINESS WITH THIS COMPANY

Scammers, bought for one month with monthly payments and they take money each week for about 5 months. Cancelled already twice and they still take the money. Avoid!

Thank you for your review. We’re sorry to hear about the ongoing charges. Please note that Certified Fasting plans work on a subscription basis, which is explained during registration and in the Terms of Service. This means payments renew automatically unless cancelled directly from your account.
If you no longer use the service, please share your registered email or user ID via the internal Trustpilot form or contact [email protected] so we can review your account and make sure everything is handled correctly.

WARNING THIS IS A TOTAL SCAM. I cancelled subscription and they have continued to take money out of my account. Only way to stop them is to get a new bank card which has been a huge inconvenience. When I contacted them about cancelling they asked me to click on the link and use the original card and they will refund. They took a further $250 form my account.

Hello,
Thank you for bringing this to our attention. We’re deeply concerned by what you’ve described, as no new payments should ever occur after a confirmed cancellation - and certainly not through any support communication. This situation must be reviewed immediately.
Please contact us directly at [email protected] or respond to the Trustpilot information request so we can locate your account and check exactly what happened. Our team will make sure it’s properly investigated and resolved as soon as possible.

Kate,
Thank you for the reply.
The most annoying thing on your entire program is that it is almost impossible to get out of the program. When you try to get out you are being trapped into many other questions and options.
Do you realise that this is forbidden in the EU? The law states that the ease of how you can subscribe should be the same as getting out or cancelling your subscription. And that is absolutely not the case in your program!.
The same as being clear who the consumer is dealing with, this should be findable within one click and the saem as who and where you're paying to.
You can say that it is mentioned on your website but it is hidden on your website, almost impossible to find and that is legally not allowed.
There are many more traps in your program and apps which are not allowed. In case you think that being settled in Cyprus creates escapes for you legally, then you are wrong too.
Maybe you should take a proper look at your reviews. The Majority of the complaints are all the same. Same as your lame excuses, giving people the idea you understand them but doing not further more with it.
I think it is time that you change your policy immediately, especially because I'm gonna make a note about this at the legal authorities.
Besides the fact of your fake positive reactions in the reviews, your website is a huge trap!
Take some actions and stop behaving like this.
Yours sincerely

If I could give 0 stars I would. The whole process of cancelling the subscription is made so difficult. I was prompted to select: I acknowledge that I have to pay 1735 Ron (340 EUR) if I would ever come back to certifiedfasting.com - that's a clear sign of the AMOUNT of this scam. During the process I even clicked on some button to get a new meal and instantly I got charged with 99 Ron. Imagine that! What a scammy site. Now I could only closet nu credit card and report the diet-cf.com tranzacționa in the hope of getting nu money back. Avoid certifiedfasting like the Plague.

Terrible app.not got the minerals tbh. If you forget to check in…
Terrible app.if you forget to check in or out of fasting it says you have been eating or fasting for days and uo and then doesn't account for these inaccuracies. App needs work and was not anywhere near worth £30 - and trying to cancel the subscription was a ballache. They make you jump through so many hoops - fricken annoying

Hello,
Thank you for taking the time to share your experience. We understand how frustrating it is when tracking doesn’t reflect your actual fasting pattern and when cancelling feels harder than it should. That’s not the experience we want for our users, and your feedback is important as we continue improving the app.
We’d be happy to take a closer look at your account and help with anything still unresolved. Please reach out to us at [email protected], and we’ll assist you directly.

Thieves! Absolutely not this is a scam! I cancel the service months ago and I keep getting charged every month then when I complain to them they make it out as if it's my fault because they sign you up for multiple subscriptions and each one has to be canceled by themselves I went back and forth with them over multiple emails and I was assured everything was canceled and yet today I find out I was charged again!

Hello,
Thank you for sharing your experience. We understand how frustrating it is to see charges when you believed everything had already been cancelled. Our plans renew automatically unless cancelled beforehand, as explained during signup, and some options work as standalone subscriptions, which means they need to be cancelled individually. Still, we want to make sure your situation is fully reviewed and handled correctly.
Please respond to the Trustpilot information request or contact us at [email protected] so we can locate your account and assist you further.
I signed up for a trial by mistake and cancelled. Received confirmation but was charge twice for subscription on Paypal.
I would give 0 stars if I could.
Beware of scammers out there!!

They still didn’t refund my money back and keep ignoring my mails. They are stalling and it’s been more than a week now. Not even polite and according to customer service! I definitely do not recommend this to anyone if you don’t wanna get scammed! I tried to stay positive and polite but apparently it brings us to no where!

SCAM, SCAM, SCAM, SCAMMER. An APP developed to scam people
First of all they even dont deserve a 1 star. This company is a scam and will definitely scammed you the moment you do a 7 day trial without any chance to cancel it and cant even open the app/site without you buying additional service, i used my paypal account and their email when i signed up for 7 day trial cannot be located and opened. Then they have the nerve to chargedm me an additional amount of $50 CAD without my permission and claimed i used their service. After the charges they suddenly have an auto reply e-mail that says they are extremely busy with high volume of inquiries but you will never get a response to your claim. Such an ultimate disgrace to scam vulnerable individual. I already disputed it both in paypal and mastercard, next i will send a complaint to consumer protection canada.Dont fall for this company ever or you'll get victimized.

A complete and utter scam to take money out of your account. The cancellation of the subscription is a complete mess. The aim of this site is to rip you off. Be very careful before putting your bank details in.
