KFC Zevenwatch Mall the worst customer service ever!

Cashier Amanda was extremely rude, she gave me attitude, and was even worse infront of her manager. She let me swipe my card on a machine that doesn't work. They told me to swipe again even though I showed them the money went out of my account. Their system showed some error. the money went off and my bank did not reverse the money. Amanda and Manager Nobuhle at KFC Zevenwatch did not listen to what I was saying until my husband stepped in and said the exact same thing I was explaining for 10 minutes. I told them either give me the food or give my money. I told them I will not go through an Entire process of getting back money when all I wanted was to buy food. The biggest load of bull**** I've ever heard. The manager kept blaming KFC for the service even though Amanda the cashier was clearly to blame. She I front of her manager told me the money going out and not reversing is my problem not hers. She is not to blame for knowingly using my card on a faulty machine. They finally gave our food because my husband stepped in. Even now my money has still not been reversed. Please repremand Amanda she is honestly the worst cashier ever. The worst attitude towards customers, blaming customers for her mistakes. Still having the worst attitude in front of her manager. Refusing to let the customer speak, and speaking over them. Saying words like chini and mxm showing she is annoyed because I the customer is upset over her service and the fact that she let me swipe my card on a faulty machine
