I was contacted by letter from Contract Callers, a debt collection agency, regarding a balance I owed to XXXX gas. The balance due was {$400.00} The letter was a settlement offer. They offered me to pay {$200.00} and my debt would be considered settled in full. I spoke to XXXX XXXX and was assured if I paid the {$200.00}, I would owe nothing else on this bill. A month after paying I received a collection letter from another agency for the remaining {$200.00}. XXXX XXXX told me my account was still open for the {$200.00} balance. I called Contract Callers and was told that my debt was only settled with them, not with XXXX XXXX - that all that happened by me paying the {$200.00} was that I was no longer in collection. My account had not been settled with XXXX XXXX and I still owed that money. They would not send me a copy of the letter I received stating that my account would be settled in full so I could have proof of the exact wording that was used. And I was told that it should have been explained better to me and that the woman I spoke to when I paid should not have told me my I would owe nothing else on this bill.
