Payment Theft

On the 16-08-2019 I had gone into the Nando's restaurant at the workshop in Durban central, upon purchasing a meal from the restaurant I had swiped my card for payment in which the manager at the time did the swipe and advised me that the card declined and was not given any slip stating the decline, however I paid cash upon returning to work I pulled out my statement which shows that the money has gone off successfully and the payment was approved. I then returned to the restaurant on Monday the 19-08-2019 to show them the statement upon giving them the statement they went back and checked and advised me that there was an error on their side and the payment did go off I was assured that this will be sorted out and was asked to return the next day for a refund. Upon my return the next day which was the 20-08-2019 I was told that they can only do an EFT into my account for the cost of the meal I immediately refused this and asked who would cover the bank chargers for this eft and was given no response all I was told was to come back again the next day. Its now the 22-08-2019 and I am still getting a whole lot of stories from the restaurant and have not yet gotten my money back nor have I been compensated for the time wasted in which I had to keep going back for the past 4 days this is unacceptable and I demand a cash refund and compensation for my time wasted running back and forth to the restaurant it seems as if this is being done to other people without them knowing is this the kind of business you guys run.
