KFC sells rotten tasting food

i bought KFC today at Midrand Mall and it was ABSOLUTELY disgusting! The oil that the chips was cooked in was so old it tasted sour! The chicken smelt and tasted off. i actually feel sick while im typing this. I am bitterly disappointed at this quality and actually stopped to throw the food out. How can you serve people this kind of food? Rated 1 star as Hello Peter doesn't allow 0 stars
