Undercooked Chicken, Severe Illness - KFC, Uplands Wales

71A Uplands Crescent, Uplands, SA2 0EX Wales, United Kingdom

I had a fillet burrito last night, throughout the middle of the chicken it seemed undercooked and strange to the texture - almost like gristle, I had a few bites before realising there was something definitely wrong.
This morning I've been sick so many times, diarorreah, can't keep water or yoghurt or anything down, I feel absolutely awful. | Symptoms: Diarrhea, Nausea, Fever, Vomiting
