Bad attitude

I visited Mr Price Mokopane on the 25th Aug for a bit of shopping after which I tried to make payment with my FNB card,the card machine returned as declined. I then used my Capitec card to make payment but as I exited the store I received an sms confirmation from FNB that my account has been debited R1759.87 by Mr Price I called the bank to confirm if this is true because the machine declined the transaction and the bank confirmed that the amount is reserved by Mr Price. I went back to the store to ask them to release the authorization from my FNB card as I already paid using the Capote card but the manager Emanuel refused saying I ultimately have to wait 24-48 hours for my funds to be reversed. Now it's been 96 hours and they are still holding on to my hard earned money on top of that I have debits going through that account except there won't be any money to debit. I called Mr Price HQ to complain but was referred back to the store and the same Managet gave me the same stinking attitude saying it's not his problem and HQ says it's not their problem either. I called FNB for assistance but they need Mr Price to send them a letter to release the hold. A letter which Mr Price has no intention of sending. All my debits will not go through thanks to your arrogance Mr Price and worst part is I will have to pay the bank returned debit fee charged to my account . Very disappointing.
