Fraudulent Bills

I was a customer of AT&T by way of residential telephone service. I began having long distance charges that I was not making on my bill in February of 2009. I started disputing these and seemed to be having luck with AT&T customer service. Then March, April, May etc. came along and I was continuing to have these charges on my bill. Hundreds of them! I had long distance service removed in April. I was still being charged for long distance calls. I finally threw in the towel and had my service disconnected in June. You would think that would be the end of this. WRONG! I just received my July bill for $67.00 -- all long distance! I haven't even been an AT&T customer since June. I am sick and tired of AT&T trying to take my money. This company is fraudulently charging for long distance on a phone number that no longer exists and are trying to get me to pay them!
