Refusal to accept returned products

I sent my daughter to buy a chicken meal which was on special while I waited in the car. She instead bought frozen drum sticks. I saw tat she bought incorrect chicken before she could even open the boot. I returned it within five minutes but I was told that they don't take back returned meat. My issue was that the products I was returning were not taken out of the shop for even five minutes. I think it is unfair for the store to treat all cases in the same way. The meat was taken out of the door and immediate back into the store. I felt so disappointed and hurt and I left the meat and the slip with the supervisor. I don't know what they did with the meat
