I too was scammed on this.Their phone number is 800-948-8488 if you want to complain but it doesn't do much good.
I was told they would submit a complaint form to their marketing dept. No guarantee I would get what Am Entitled to. I've attached a snap shot of my confirmation showing I would get emailed and code for the pizza but did not. Spoke to a guy named Patrick and he kept apologizing but unable to do anything else.
apparently it was not valid for pick up but this is the first I've heard of this.I will never go to Pizza Hut again.
