Hometown Productions AdCom Ripped me off on advertising magnets with Pizza Hut Arlington Texas

I was called in July, 2014, and told that for $300 I could pick a local Pizza Hut that would distribute magnets bearing my advertisement, in every box of pizza taken out of that location.  I was told I would be given 200 complimentary magnets in addition.  I asked how many magnets Pizza Hut would be given and was told "as many as they need".  I paid them with my American Express card and told the lady I would be checking to make sure they followed through with their promise. In early September, I disputed the charges because I had received nothing and neither had the Pizza Hut.  A few days later, I received 20 cheaply made magnets, not the 200 I was promised. 

I have been to Pizza Hut 6 times, with today, January 29, 2015 being the most recent.  No one there has ever seen one of my magnets and the manager told me she hasn't seen a magnet go out in a box of pizza in the 32 years she has been there.  She has never seen my magnet, either.  I have disputed the charges at least 5 times and every time I do, Ad Com comes back with another lie.  The person who supposedly signed for the delivery at this location, is unknown by everyone who works there, so I believe AdCom made up a bogus UPS tracking slip.  I went online to UPS and put in the tracking number several times and I got an "invalid number" message every time!  Do not order any magnets from anyone telling you Pizza Hut will distribute them!
