maggots in the kfc chicken

i bought KFC from the KFC Phoenix - Northern Drive, which was the fiesta meal. while having the meal , i found maggots inside the chicken. i have pictures of it. i then call in the branch and was spoken rude to and hang up on.the manager did not care that there was maggots in the food , all she said was its nothing she can do, i got the recordings of then call. she wanted to replace 1 piece of chicken, what if the maggots was on all the pieces. i got sick from it and had to go to the doctors , my 2 year old child also ate this food. i advise people to check their food from this place , because they use old chicken , it tasted funny and and no flavour. KFC is gone bad to worst.
