Payflex Taking money without Authorization

I have send 2 very detailed emails requesting Payflex to remove a card that they continue to take payments from. I do not use this card anymore, therefore that card does not have a balance on. Due to this, I constantly get charged for "Declined Purchase Fee" from my bank.

After two very specific emails, they still ignore me, and claim that my email address don't exist. On their app I have no way to remove a card. I do have an active card, which is selected to use as the primary card. But this is not actioned by them and they continue to take money from a card that I do not want to use. I have emailed them and had a reply from Tebogo, but totally ignored my request and claimed to be unable to help me.

I do have an active card on there. I only want to remove an unused card. But they refuse, costing me lots of money in declined transaction fees. And their support and user experience is just non-existent in helping me.

There are plenty of other similar services, the competition is big. Why have an app and user interface of such poor quality is only bad for business. I will now report them as *****ulent transactions. I specified very clearly not to take my money from that account, I did not give them permission, they still do, so now it becomes ********.
