Spoiled food at KFC

I bought 2 kiddies meals and twister at KFC in Blu Valley shopping center in Centurion. The lettuce looked spoiled. The taste was worse. I had to throw them away. I don't understand why they had to sell me that kind of food. They saw when they were preparing the food that, it's spoiled but they still went ahead and gave me spoiled food. All my money gone. Mxm
