Promised a TV if we switched from Charter to UVerse..Never received the TV

We were told that if we changed everything over from Charter to Uverse we would recieve  a free TV.  My husband called one month after we had the Uverse service to get the TV, just like the had asked.  My husband was passed around to about 10 different people, each not knowing what he was talking about.  To me that is false advertisement.  How do we get our TV.  We changed our phone, internet and TV.  We would love to recieve the TV we were promised!!!!
