R2200 MRP app purchase DISASTER!

R2200 taken off my bank account through online purchase on the MRP app via card payment. The app kept saying “processing”. FNB app confirmed online purchase during transaction and then the app continued to lag stating “processing.” When I went back to the app there is no evidence of purchase, The item is still saying it’s in “my bag” therefore not processed on MRP app but my money has been taken off my account. ‼️ It’s extremely hard to contact Customer Care telephonically although I’ve called twice, no one has returned a call, no email.. nothing. I have contacted via WhatsApp too and no action has been taken. It’s been a week now as I made my purchase 29 Jan. I only did this purchase online as I am aware online purchases get delivered quickly and now I’m waiting a week with absolutely no repose from MRP whatsoever.
