Pizza Hut Never Issued Promo Codes, Internet

Pizza Hut.com promoted a free P'zone with the purchase of a pizza online.  To receive the code for the free P'zone, I was required to either Like Pizza Hut on Facebook or submit my email address.  I read all their requirements & followed them, but never received my code for free P'zone.  I emailed their Corporate offices, but never received a response.  I called their Corp. offices 3 times & was assured each time that I would receive my code by email within the next 24 hours, but never received any code.  I'm disgusted with them & with their lies & plan to boycott them & tell everyone I know to do the same.
