Charging credit card service fees in error

Standard Bank is driving me totally insane at its incompetence. So let me try again...<br> <br> I notified Standard Bank a while ago via secure message and over the phone that we pay a monthly lump sum for our service fees, which includes the service fees of the main and secondary card holder credit cards. They are debiting us for credit card service fees in error. They explained that the wrong credit cards were issued by the bank and that we should have had Titanium cards. The personal banker at the Westgate branch agreed to issue the correct cards, but refused to refund the credit card fees charged in error and paid by us!!!<br> <br> They have AGAIN charged for credit card fees and no new cards have been received!! I sent another secure message - no response from the Westgate branch. I received a response from the Call Centre 21 hours ago requesting additional personal info which I supp**** immediately. No further response.<br> <br> Please tell me what I must do to correct this mess?
