There isn't a way to contact AT&T about rewards card
I have AT&T internet and was promised two $50 rewards cards. There is only one $50 rewards card sitting in my rewards center. I have called the AT&T Reward Center customer service line (800.288.9983) multiple times and have hung up after sitting on hold for 45+ minutes each time. AT&T persuaded me into signing up for their service by adding that extra $50 card and it seems like I was lied to just to gain my business.
