KFC Malvern Bad Service

Due to KFC Tuesday's hot wings special the store was busy. Had to wait about 45min for my order which was incorrect. Ordered 24 wings received 20. Ordered plain graves and they were only filled half way of the tubs. Bought streetwise 6 pieces and chicken was not fully cooked. When approached staff named Zama and she had so much attitude when i showed her the gravies were only filled half way and the third was filled to the top. She said thats the way it is and if im unhappy she can take some out from the 3rd one to make it match. I spent about R250 and the service and attitude was horrific. Very disappointing
