Mould on burger bun

Hi<br> <br> I ordered a KFC Zinger burger for lunch from the Chatsworth center branch, however when I got home and started to eat it I noticed the bun tasted about old and when I flipped the bun I noticed some green mould on the bun, I immediately took photos and called the store and the manager apologized and said they will send me another burger, I then called the regional manager and he then went to the store to investigate and called me back and told me he will send a family meal for me. The family meal took 1hr and 15mins to get to me.This is totally unacceptable cause if I hadn't flipped the bun over I wouldn't have noticed it at all and would have just eaten the burger. I was shocked cause I didn't expect something like this from KFC after all. Thank God it wasn't a child cause they would have just eaten it. I am going to share this with family and friends as well as put it on Facebook and other media. <br> <br> I await your kind response.
