Waited for almost 2 hours just to get attitude

We went to KFC N1 city value centre and had to wait almost 2 hours in the drive through due to only 3 people being staffed. When we finally got to the front, their tills didn't work, they took the order manually 4 times and two people had to take it, because they couldn't get it right. I was patient throughout the process, but when I finally asked how long it would take, I was ignored and when I asked again, suthu who denied her name and said she was bongi, gave me attitude. When I expressed my dissatisfaction, there was no apology until I had to ask for one. To top it off as a result of waiting so long and having my lights on, my car battery ran flat and I had to get the AA to come out. Whilst waiting for the AA, there was another altercation with the staff and other customers and I was appalled at how the staff shouted at customers. To make matters worse, they still got my order wrong and I realised this at home and the burgers that we got had overcooked chicken. This was by far the worst experience ever at a KFC.
