Chaared and contaminated food to a sick person

We order kfc for my son who was in hospital in randburg ,the kfc was contaminated and chaared it did not taste well at all ,please remember that kfc might be serving doors to people who re not well we don't need them to further contaminate the food andcrisk poisoning or hurting and I'll person already ,watch what u serve the public ,your quality is slowly dropping..I'm disappointed
