I have reached out to you previously ( Case # : XXXX ) on XXXX XXXX, XXXX, and I have received no reply to my problem with XXXX XXXX XXXX. On XXXX XXXX, XXXX, I paid off all my XXXX XXXX XXXX which were held by XXXX XXXX XXXX  with a payoff amount, emailed to m on that date by XXXX XXXX in the amount of {$370000.00}. I received Paid in Full Notifications on XXXX XXXX, XXXX and XXXX XXXX, XXXX. On XXXX XXXX, XXXX I received a welcoming letter from XXXX XXXX saying I owed {$50.00} on my account which was paid off. I called XXXX XXXX XXXX many, many times and was told they could n't explain the problem. I finally got a supervisor, XXXX, who worked on my case and I said that while XXXX XXXX now said I owed XXXX, I really only owed {$7600.00}. On XXXX XXXX, XXXX, through a divorce settlement, this amount was paid to the Dept. of Education and became part of a legal document, with a letter from XXXX XXXX XXXX saying that if I paid this amount, I would be paid in full. On XXXX XXXX, XXXX, I received a call from a XXXX from XXXX XXXX XXXX, saying I owed {$2900.00}. When I asked how this could be, she could n't explain it but said I owed it. When I asked for an explanation, I received a letter dated XXXX XXXX, XXXX saying that I cashed a check which came to me from DOE in XXXX XXXX and I really should n't have gotten it. When I begged to differ and asked for further investigation, I received a letter from XXXX XXXX XXXX on XXXX XXXX, XXXX, that I owed {$59.00}. I received another letter from XXXX XXXX XXXX on XXXX XXXX, XXXX, that I owed the same amount and they were still reviewing. On XXXX XXXX, XXXX, a XXXX from XXXX XXXX XXXX called me and told me to pay the balance of this amount and then my account would be paid in full, so I paid {$67.00} that very day. On XXXX XXXX, XXXX, I received a Paid In Full notification from XXXX XXXX XXXX. On XXXX XXXX, XXXX I received an invoice from FedLoan Servicing that I owed {$2900.00} again. I would continue to get monthly invoices with this amount until XXXX XXXX, XXXX I received a notice that I owed {$18000.00}. I disputed this amount as there was no back up information as to how XXXX XXXX XXXX arrived at this number and that the number continually changes, etc. XXXX XXXX XXXX then sent me a schedule as to how they got to the {$18.00}, XXXX, which was just entering numbers saying " error - consolidation ''. At my request, it was then sent to a specialist at XXXX XXXX XXXX, XXXX XXXX who was working on my account from XXXX XXXX, XXXX to XXXX XXXX, XXXX, when he called me and said that FSA said I owed the money and had to pay it to XXXX XXXX XXXX. He then sent me a letter dated XXXX XXXX, XXXX, which was not received until XXXX XXXX, XXXX and then another letter dated XXXX XXXX, XXXX with repayment options. All the while, I have been charged daily interest charges on their bogus claim. There was no back up documentation whatsoever ; just this answer and I was expected to begin some type of payment to them immediately or be charged daily interest which is what they are now doing. I have collected numerous reports, etc., to outlined how XXXX XXXX XXXX changes numbers and dates at will and then tries to explain these lies. I have paper proof of their lies and would like some type of resolution to this matter. To make matters ridiculously worse, I received an invoice from XXXX XXXX XXXX that I now owed {$16000.00}, again with no explanation, just a change in figures. Would anyone in their right mind, continue to pay this criminal organization? I certainly ca n't.
