Terrible customer service

Good day,

On the 25th of January 2025, I placed an order with a merchant that makes use of the Payflex Payment option. As soon as I paid the first payment due, I noticed that I did not get a confirmation email from the merchant stating that they received my order. I decided to email the merchant directly to enquire if they received my order to which they rep**** that they did not. The merchant has been trying to follow up with Payflex as well as myself regarding the transaction. The merchant also confirmed they did not receive any payment in their bank account. There is no way of getting hold to speak to an agent at payflex. They do not answer calls at their call centre then not even going to mention about emails. Worst customer service I’ve received in a long time.
