Deceptive advertising

I ordered a pizza from Debonaires Princess Crossing and it was cold and disgusting. I complained and wanted to return it but the store manager **** to me and said that the next time I order I will order for free so I ended up eating it anyway since I was hungry. About 15 days after the incident, I try to get my free order and call the store manager and he tells me that I can only get a side for free not my entire order. Debonaires must stop using the deceptive slogan that "if your pizza is cold, you get it for free".
