I had an account with XXXX from XX/XX/XXXX to XX/XX/XXXX. I sold my house and called them to inform them I was cancelling service. They informed me I was no longer under a service contract and it would not be a problem. I thought the matter was over but I recently checked my credit report and discovered they were reporting a balance in the amount of {$900.00}. I called FIRST NATIONAL COLLECT and they informed me they did not have any details with the account. I then called XXXX and they said it was due to early termination. ( I had this account for more than XXXX years ) Then, they said they never received equipment that needed to be returned. I talked to a supervisor that said he would adjust the balance to {$220.00}. I called today and the balance is {$900.00}. I spoke to several reps with XXXX and nobody can give me any answers. I need help in this matter because I paid the account as agreed.
