Spoiled and burnt food

I received my order on time, infact early which I was really happy about. Then I opened the order to start eating and found 2peices burnt and turned upside down, as if hidden, on further eating we found that 3 more pieces of chicken did not smell right and on further tasting it is was infact spoiled. I then contacted your Phoenix branch and spoke with thokozile(she stated that she will consult with the branch manager and said he Stated that they will replace what was not eaten, I explained I don't want to order again as I was not happy with the meal and requested that I received a refund of 50%of my order. They said they will get back to me, I had no one call me , so I called again on the 18 th , on speaking to another lady I was assured that the area manager will contact me, to date no one had called me, I am now going to post my complaint on hello Peter . It would not be the first time that KFC has disappointed me
