Foschini Valhalla

I have tried to buy shoes at foschini valhalla. The lady at the cash register kept on moving me from one cash register to a nother. At the last point she said that the terminal is not freezed over there and that she can help me. After the payment went through according to an SMS from the bank. The lady at the cash register just explained that the terminal freezed and that she is sorry, she can not give me the shoes. I showed her that it went through but she just keep on explaining that the terminal freezed. Now I paid R300.00 and didn't get my shoes. It was clear to me that she stole my money right before my eyes in clear day light and I can do absolutely nothing about it. I am very upset!
