Worst service ever

My wife bought KFC on Friday 13/11/2015. The guy that took her bankcard for payment was in a hurry and didn't wait long enough for slip to be printed, so he said he will put the transaction through again and the payment went of twice. Then he tells her she must come back the next day for a refund. So the next day, Sat(14/11/2015), my wife goes back with proof of payment, to see the manager for the refund. The manager told her it was the banks fault and that the bank must refund her. So then my wife explains that the transaction was put through twice on the card machine and that the bank will not refund her for their mistake, at this point the manager started giving her attitude and told her that she had to get a bankstatement ( Which will cost us more money) so that she can proof the double billing. Today I went there myself and was probably more intimidating than my 50kg wife. Calling the manager with the bankstatement in hand (R8,00 ****ing later) Had to hear it will be sent through to head office, where they will then contact me for a refund. She took the statment and left without getting my information, so that the \head office"can contack me. Friday13/11/2015 last KFC ever """
