AT&T/DirecTV Advertised Miles and Visa Gift Card

I was offered 25K miles on AA for starting new service with Directv/At&t. After calling aroud for weeks without getting the points added to my AA account, an at&t representative apologized and said I qualified for a $200 Visa Gift card and she'd throw in a extra $100 for my troubles (She clearly saw all the notes on my account).  

Never received either, the gift cards or the points. Just called At&t and was told my claim expired! What?! I was told something was sent to me via mail.  I never received anything other than my BILL from At&t! Nothing about a claim or my gift card!  So you mean to tell me I receive constant communication from them via mail, email and online account alerts but this important "form" didn't arrive!?! Give me a break and admit to your shady business tactics.  Wondering how many other people have similar experiences and if any class action lawsuits are already in the works.
