Payflex feels like a ****

I placed 2 orders with Makro, the first order was paid and completed and have all my items. On my second order I was not happy with the order which I returned to Makro, they then refunded payflex. Payflex then credited the order which was paid in full and still taking money for items I don’t have. I have tried contacting them for assistance however they lack understanding.. now I’m still paying for items from Makro that I don’t have. I have sent payflex my bank statement as well.. they so ***********
