Old KFC Re-heated/warmed and sold

I ordered the Famaly treat today from KFC Eastlynn via Uber eats this afternoon. I have never tasted anything this old and dry. The meat smell tasted like something made yesterday , coleslaw, chips and mash tasted like something that was put outside the for 2 days. My son's stomach is starting to get cramps and he is clearly in pain I hope this is not serious. I will never order KFC again as the smell makes me sick.
