KFC disgusting worms

I am disgusted by kfc and they chicken the review i saw on Facebook a while back i thought it was false but when i experienced it myself and for the fact that the manager did not made me more upset. When i ate my chicken it was rotten on the inside with even worms coming out i instantly lost my appetite but yet the manager decides to give me another chicken after seeing worms really which human will still eat chicken at all after an experience like that. I am horrified.
