i am unhappy with the food i received.

I bought the Chicken Box With Small Drink for R49.90 and asked the till operator to give me a hot meat that consists of a thigh, drum stick and a side breast but instead I received a wrong order which was the masala crunch box with one side breast and center breast and I didn't enjoy it at all, I couldn't even return it back at the shop because my lunch was already finished, I am so unhappy because I lost my money just for a meal I didn't even eat at all. I didn't expect this from kfc rosebank.
