On XXXX XXXX 2015 I received a settlement offer letter from XXXX XXXX in regards to my car loan debt. I reached a settlement offer and they emailed me a settlement letter to be paid by XXXX XXXX. I called them on XXXX XXXX, 2015 and paid the full settlement offer with my debit card and it cleared my bank. Then on XXXX XXXX, 2015 I received another email from XXXX XXXX acknowledging that my settlement was paid in full and they would be reporting to the credit bureaus. By XXXX XXXX, 2015 my credit report was hit by XXXX XXXX showing the my debt was " Closed '' and " Paid ''. On XXXX XXXX, 2015 I received a phone call from a third party debt collector named XXXX XXXX XXXX stating that XXXX XXXX sold my debt to them and they were trying to collect my old settled out account. XXXX XXXX XXXX did not show I had made any payment. I forwarded on my settlement offer and paid in full letter I received from XXXX to prove that I had in fact paid and settled out that account a month before they even sold it off. I then called XXXX XXXX to clear this up. The rep with XXXX did show on my account it had been paid and closed in full and they do n't know what happened and why it got sold after the fact. They said they would get it taken care of. Then today, XXXX XXXX, 2015 XXXX XXXX XXXX calls me back trying to collect the debt once again. I explain my situation again and they then acknowledge they received my emailed letters showing I made a payment and that they did try to reach out to XXXX XXXX about my account and they still had not heard back from XXXX I then called XXXX again on XXXX XXXX, 2015 to double check on my account status and to let them know I am still getting calls from their third party company they sold my account to. They advised me again that they were going to get this taken care of and would reach out to the third party collector in regards to my account. They again verified that yes my account was settled and paid in full and this Third Party collector should not be trying to collect from me. I am filling out this complaint because after going through all the legal and proper steps to reach a settlement, pay off settlement, and my credit report being hit for closed and paid status shows how XXXX has not abided under the Fair Debt Collection Practices Act.
