Now that we have all these forums, can any one tell me how to find the AT&T mailing address. I have called at least 3-4 times since signing up for a bundle, which includes U-Verse. My bill have gone from $214.00 per month which I agreed to at a physcial AT&T location close to my home. I have NEVER seen the $214.00 bill. I call and complain, and it moves down. The 2 months later it is back up. Now, again, back to $280. I am not using that much data. PLEASE someone help me. Needless to say, when my contract expires I will run....and not collect 200 dollars.
