Burger King review: food

I went to my local burger king to get meals for me and my family. I ordered my wife a number 7 and an extra sandwich. They charged me for two number 7 meals before i realized that happened. They gave me both meals however, I told them that I didn't want the second meal I wanted just the sandwich which is significantly cheaper. i asked if they could fix it and they told me no. I was not very happy with the customer service. It doesn't seem they care about their customers.
