*****ing from Clients

I went to Centurion Edgars on Friday. The first purchase I did was for a perfume, the second was for clothing. First purchase went through fine, the second purchase, just before the till slip could print another cashier opened the till resulting in the slip not printing but the money did come out as I received the sms. However, I insisted on a cash slip just in case I needed to exchange something and everyone knows Edgars does NOTHING to help a client!. The cashier could not re-print the slip so she called Nathaniel the risk manager and told him what happened. , his attitude was pathetic acting as though I didn't pay the money for the clothes. They did see the sms that the money went out he says know its a system problem and he money didn't come out after knowing how this issue was caused. Then he refused for me to take the clothing, he said the only way I could get the clothing is if I paid again, I already wasted so much time so I had no choice but to repay. I asked him for his details as well in which he gave me attitude about. He said the issue would be resolved first thing Monday, I heard nothing as yet. I want my money plus the transaction fee. I checked my bank statement
