KFC makes me sick !

It seems as if the KFC at pavilion mall durban serves a different product. Today I purchased from there after being in a hurry (fast food),after a long time because of previous bad experiences. I had severe stomach cramps and diarrhea after eating that nonsense they serve. It was darker in colour than normal and also oozed with water when I cut it. This happened to me so many times and only from kfc pavilion. I often purchase from the queensburgh branch and never had an issue. You guys are messing with peoples health - please get it right especially during these times. Old oil or old chicken?
