SIMPLEX...SIMPLY THE BEST!
What I like most with Simplex is it's fast processing. Then sent you notification every transaction and ask you if transaction was fulfilled and if not a link to a support team is always made available.

Hello Mohammadali, Thank you for getting in touch. Please note that for internal reasons, we are unable to proceed with your recent transaction and the payment was refunded. Based on our internal guidelines and policies, we are not always able to provide the exact reasons why, this is to ensure that our customers and our data are protected. In this case, you may try and issue a new payment, however, since the payment process is fully automated, we are unable to override our system’s decisions, therefore we cannot guarantee it will be successful. We apologize for any inconvenience this may have caused and thank you for your understanding. Regards, Julia Head Of Customer Support

Used Simplex before without any issues
Used Simplex before without any issues, completed verification in the past and everything worked normally. Recently I transferred €1200 to my Simplex account, after which they suddenly requested additional verification. For 2 straight days I was stuck in endless KYC checks — one document rejected, then another, then another. After finally providing everything they asked for, I was informed that an additional source-of-funds verification was required. I submitted all requested documents immediately. Support told me the review would take 48–52 hours. It has now been over a week since my first request and there is still no resolution. What is worse — once I started asking for explanations regarding the delay, support simply stopped responding. At this moment: I cannot use my funds; I cannot transfer them in crypto; I cannot withdraw them back to fiat; I cannot even close my account. When I requested account closure and return of my money to my bank account, I was told to “wait for the review”. No deadlines, no explanations, no accountability. This is completely unacceptable for a financial company handling customer funds. They violated all promised timeframes and now ignore support requests entirely. If I do not receive either my funds back or a proper explanation within 48 hours, I will proceed with legal action and formal complaints through banking and consumer protection channels. Very disappointed.

It took more than 24 hours to get my crypto currency that I purchased, with no real help from Simplex support team, a bot that tells you, "that is all I am capable of doing" very disappointing, poor and nerve recking process and customer service. Thank God I finally received my crypto

Hello Howard, Thank you for the review. I have thoroughly reviewed your recent payments and can see that the cryptocurrency you have purchased has been successfully sent to the destined wallet address from our side. I would like to elaborate that we do always strive to deliver your coins with the utmost urgency - however, in some cases, this can be delayed due to factors which are outside of our control, such as the demand for the cryptocurrency you are purchasing, the number of miners available, and the volume of transactions occurring on the blockchain at the time of your purchase. However, if the cryptocurrency does not display in your wallet correctly, it would be helpful to reach out to the support team of your wallet provider. As much as we would love to help, we do not have direct access to your cryptocurrency wallet address or account, therefore, we cannot solve issues related or originating to/from your cryptocurrency wallet. Thank you very much for your patience and understanding! Please let us know if you have any further queries. Regards, Julia Head Of Customer Support
