PAYFLEX STRIKES AGAIN. NO SUPPORT

And Payflex strikes again. This is my second time having an issue and my email or calls go unanswered.

I paid for items with Makro and paid the first debit. The payment was not successful on Makros side but the payment plan is set up on Payflex.

Do you even have employees? Can someone please resolve this urgently? Why does such a big company fail at basics?
