Bad service at till point

On 20 May 2015,my wife and I was shopping at Fruit and Veg City in Newton Park,Port Elizabeth.We payed for our goods at the till point using our Debit Card.Our cellphone responded with a message,telling us the sale went through,and that the money was taken from our account.Upon this the cashier at the till point told us that the sale did not go through,since it did not reflect on the slip that came from the swipe machine at the till.We told her the money was taken from our account.She responded by calling her supervisor,and the supervisor called the Manager.I explained my situation to the Manager,who couldn't give me an straight answer.They told us the money will be reversed by the Bank within 2-3 hours from that time ,and that they had to swipe the amount of again,which they did. It's the 21 May 2015,and the money has not yet been reversed by the bank as told to us by the Manager of Fruit and Veg City. I think their service and attitude was really pathetic.
