I've been with AT&T for over 3 years. Had DSL, recently switched to internet air. No complaints with internet air. However, the billing overlap is outrageous. I was told there would be a 7 day overlap... OK, I understand that. Instead of a 7 day overlap I'm being charged for a full month use of DSL and a fill month for internet air. Both for the same billing cycle. I called customer service... the representative basically laughed at me and said I should have read the fine print. I did, it said 7 day overlap. This man informed me that I would be charged for both since the DSL account was canceled and it is not AT&T's policy to prorate charges. I asked him if the bill was paid a month in advance, he said "I think so". I said back to him, " do you think so or is it company policy?" Again, this man laughed at me and asked did I want to argue over semantics. Really??? AT&T... you need representatives who know what the policy for your company is as well as training them on how to be professional. I don't expect to be billed for a service that was not used!
