How do i report little ceasars

Harley

How do I go about reporting little ceasars because today when I got one of there pizzas there was a thin piece of metal in it and when I called and talked to the manager she was very rude towards me and told me she would not replace my pizza because we have had past problems with thier pizza being either burnt or not cut which it's like I told them I was not complaining I just wanted to let them know what was wrong with it so maybe they could do it better for someone else but this time I expected them to fix it but was told that it was my fault because they don't use nothing metal
