Cingular Wireless ripoff unauthorized upgrade & contract Ocala Florida

I signed for my son a one phone one year contract in 2001. My son went back after that year. he got another phone & a new two year contract. Then he went back & got two phones & a two year contract. He had problems & did not live up to the contract. I was billed for a cancellation fee on two phone contracts & unpaid charges. I would have been happy to pay for the unpaid charges on the one phone I signed for, but I did not agree to the other. I had told this to the Cingular rep. when I talked to him a long time ago. I thought everything had been taken care of & forgiven. Now I find myself turned over to a collection agency that is very rude. They say my s.s.# & signiture is there, so I am responsible. I told them it was the same as if I sign for a loan & the person I signed for can go back & get as much money as they want & change the terms without my permission. To me this is the same. They said it has nothing to do with it and they did't want to discuss it. They said I owe the money and that's all there is to it. The contract I signed for was completed as I had promised. I had a contract with them myself & it was completed. Where is the good customer service & why did I not have to sign for another contract?
