FOOD POISONING AND ZERO REFUND!!!!!!!

I'm disappointed by the food quality here, there was a horrible metallic taste in all my meals when I placed an order, I went back to the store and advised them I want a refund but was blatantly told no they can rather make me another meal, so they made me another meal and guess what SAME ISSUE I seriously cannot deal, I better not have food poisoning right now, but I'm 100% never going back to this KFC ever again....KFC Banbury!!!!!
