Pizza Hut False advertising and empty promises Internet

Pizza Hut continuously advertises offers that don't exist. For example, "50% off ALL menu-priced pizzas." or "$11 ANY Pizza". However, when trying to place an order using these offers, only a very limited selection is avaiable. They do not mention the exclusions even in their fine print, and even capitalize the words "ANY" and "ALL". They responded to 1 of my 5 contact attempts, and took over a week to do so. And after that week all they said is that it was a glitch and it will be corrected. A couple months later however, and the "glitch" is not corrected and the false advertisements continue. After I submitted complaints to several agencies, Pizza Hut's corporate office chose one of their franchisee's to deal with it. The franchisee contacted me promising free pizza coupons which never came in the mail. My next contact with the franchisee promised a call back. Still nothing.
