Collection firm purchased debt in 2008. Date of XXXX delinquency and reporting date was XXXX 2008. XXXX year credit reporting expiration should have been XXXX XXXX. I have recently checked credit to see the dates have been changed to XXXX with 7 year expiration moved to XXXX XXXX. I have had no direct contact with Asset Acceptance nor have I done anything or received information that would have moved or changed any aging on this account. I have previously asked multiple times ( in writing, certified letter ) for a full debt validation, including original dates, etc. They provide a very generic form which is not a validation, but rather a verification that my name is listed on the debt. This is causing continued damage to my credit. What they are doing is illegal under the FDCPA
