Advance Collection Agency accepted an invalid claim for rent overpayment from XXXX XXXX XXXX ( XXXX ) and did not provide me with valid verification of the claim. In XXXX, 2014, XXXX XXXX XXXX informed me that the check issued to me on XXXX XXXX, 2014, for Housing Assistance Payment ( HAP ) was an overpayment and that I had 10 days to repay {$590.00} or the debt would be sent to collections. The letter did not acknowledge XXXX own letter of XXXX XXXX, 2014, ( attached ) which verifies that my contract was valid on XXXX XXXX, 2014 and would remain in effect until XXXX XXXX, 2014. There was no overpayment because at the time the last payment was made, the property was still under contract. Five months later ( After I had sold the property and no longer maintained an address in XXXX XXXX, XXXX sends a fabricated ledger statement with false dates to Advance Collection. Advance Collection did not investigate the claim and when I had a lawyer to call Advance Collection, there was some indication that the same staff member at Advance also worked for XXXX XXXX XXXX. I disputed the claim immediately, writing to XXXX XXXX, the Regional Director at HUD, and finally the Commissioners for XXXX and copied the last letter to Advance. Again, with no investigation or response acknowledging my dispute, Advance Collections placed a negative report on my credit report. I attach XXXX documents to show that XXXX claim for overpayment on XXXX XXXX, 2014, is not valid because the contract was not cancelled until XXXX XXXX, 2014. The second is to Advance Collections to inform them that the HUD regional office had suggested I contact the XXXX Commissioners about the dispute. The debt is not valid. The collection agency did not provide me with authentic and accurate verification of the debt and I was initially told by telephone that the amount was for repairs that I had not paid for. I am requesting that the negative report be removed, that relationship between Advance Collection and XXXX XXXX XXXX be investigated and that Advance Collections be reprimanded for its practices.
