Horrible experience and no reply from call centre

I often eat KFC and me and my friends came back from an event at about 10pm we decided to get KFC. When we arrived at the drive through the cashier told us we can only have 2 twisters and there was only a zinger patty so we ordered a box master and 2 twister meals as well as 4 dunked wings. After the order was made we were asked to wait in the parking lot as it would take about 7 minutes. During that time my girlfriend went to the bathroom and said she has never seen a ladies bathroom that dirty before. We waited over half an hour while most of the staff were sleeping inside. When the food finally came it was horrible, chicken was extremely dry, the twisters had hardly any filling whatsoever, the lettuce was old and brown on of them didn't even have tomato. The wings had almost no sauce and were soggy. We didn't finish our food and gave it to the dogs when we got back. I have not eaten KFC since. <br> <br> I then called the customer service centre to lodge a complaint and was told I would be contacted by a representative. I have followed up but still have not been contacted. How can a call centre not tend to a complaint? Is that not their job?!
