Bad attitude and customer service

I complaint to the manager at KFC Bloem1 on the 30th of May about a double charge on my account. The previous night, the manager Thabang promised me that the mistake will be rectify within 4 hours. However, this never happened and my money was never transferred to my account. This is not the first time it happened to me at a KFC. I asked him to write a formal letter stating the above of which he did. At 12:50 p.m the day shift manager was very rude. Firstly, he refused to give me his name so that I can lay a formal complaint. Secondly, he had a serious attitude problem. He spoke very aggressively to me in front of other customers and said someone else will resolve my matter and not him. He said I should go to head office. He simply refused to resolve the matter using an aggressive tone of voice. Telling me that he has been working with customers for the past 10 years and I should not tell him.<br> <br> As a regular customer I am terribly disappointed in the way I was treated. I will never buy at KFC Bloem1 again.
