I upgraded an existing DRY Loop account that I had for 7 years. I have been making payments to that account for 7 years. AT&T decided to give me a new account number and change the billing rate for my DSL. Now I have two bills coming to the same address, one is in arrears and I do not know what is happening to the other account. It is impossible to get through to AT&T and there is no customer service address listed anywhere to send a letter. Does anyone have the same problem? How did you get AT&T to correct it?
