Hello Jo,
Thank you for getting in touch.
From what I can see, it would seem that you might have been a victim of a scam. We would like to highlight that Simplex is a payment processor for fiat-to-cryptocurrency purchases. Our main activity scope is secure payment processing and fraud prevention.
As a regulated service in the EU, we take extreme measures to ensure the safety of all transactions that are sent to us, stopping thousands of fraudulent payments on a daily basis. I am sorry to hear that your case might have been different.
I can see that your case has already been transferred to our analyst team for further investigation as well as assistance. You might be asked relevant questions or asked to provide some additional information for a better understanding of your case. I’d like to ask for your ongoing patience and collaboration with the relevant team.
Thank you for your ongoing patience!
Regards,
Julia

Hello Leonard,
Thank you for the review.
I am truly sorry for the difficulties this situation has caused. However, please be informed that the transaction was not declined from our end - instead, when we tried to place an authorization hold on your funds, we were declined by the card issuing bank before we could do so, thus rendering the transaction unsuccessful.
We would absolutely love to process your payment, and have no reason to decline it on our end - therefore, we would kindly ask you to get in touch with your bank to double-check the aforementioned criteria:
- Ensure your card is eligible for international transactions.
- Confirm that you have enough funds in your account to complete the transaction.
- Verify that your bank supports cryptocurrency purchases.
- Make sure you are enrolled in the 3D Secure program.
Additionally, you may try issuing a new payment using a different card from a different bank, if possible.
Thank you for taking the time to do so in advance!
Regards,
Julia

The transactions are declined despite sufficient balances. The transactions never reached the bank as informed by them. Message on Simplex says the transaction declined by bank.

Hello,
Thank you for your review.
I have thoroughly reviewed your latest transactions and can see that they were declined due to internal reasons which we find ourselves unable to disclose. Please be informed that the decision to decline your payments is made by our automated system based on various internal reasons and cannot be manually influenced or predetermined.
I’d like to highlight that we are a regulated financial services and our main activities include secure payment processing and fraud prevention. While we can always provide information about the status of our users’ payments, we are not always capable of disclosing the exact reasons as to why certain transactions may not have been successful.
You are welcome to issue a new transaction, nonetheless, we are not able to guarantee the success of your future payments.
Thank you for your patience and understanding.

Julia

SCAM!
SCAM!! I’ve tried to do 3 transactions within the same day and none of them arrived to my account. All three were withdrawn from my bank accounts however. It’s 16 hours later and still nothing. I’ve been in touch with them and nobody has reached out. Why use you for crypto when the reason I use crypto is because of the transaction speed… completely useless company
