Payflex has ****** my money

I have been trying to reach PayFlex since 25th of July. Emails they don’t respond, I have sent a few. When i call their landline it gets cut off, after a message stating that they are receiving high call volumes. I placed an order on the 25th of July for gym gear on Makro, Makro stated that payment was unsuccessful, no goods have been delivered to me to date, yet Payflex took money from my bank account. I just want a refund, otherwise I will be paying 3 months for something that is not even in my possession, this is frustrating. I can’t go to Makro to fight with them because payment was unsuccessful and no email with order confirmation was sent to me.
