I was recently contacted by allied interstate claming that I owe 771.00 to AT&T. I did pay the amount I KNOW I owe them. However, the majority of the debt happened when someone who was working for AT&T didnt know what they were doing and messed up my account, leaving me responsible. I was asked to mail a detailed letter of dispute to Allied to be forwarded on to AT&T on my behalf. I recieved a phone call 2 days later saying that AT&T did not agree to my dispute. I asked for a copy of the response. When I did this the rep began yelling and bullying me.
