I feel you!
Read what I had to go through for 3 months here and then after I got it all straightened it out and got a credit on my account, they tell me I need to go to UVerse or not have internet:
»How do I talk to AT&T Retention?
»AT&T Switching me to UVerse without my permission!
I talk to AT&T today and they guaranteed me on the phone I won't be double billed for DSL which was deactivated last Thursday and UVerse which was activated last Thursday.
I guess we will see when the bill comes!
