On XX/XX/XXXX I filed a proper dispute on an unknown medical account with Experian. On XXXX/XXXX/2015 I received a response to my dispute stating that they will not re-investigate the dispute because it was previously disputed in XX/XX/XXXX, more than two years prior. I then contacted the reporting collection agency with a dispute and request for validation on this unknown medical account as per instructions from Experian, re-disputed to Experian with a copy of my dispute/validation letter to the collection agency, along with proof of the agency 's receipt of the dispute. Experian 's refusal to properly investigate the dispute is a violation of the FCRA and FACTA. Experian is the only credit reporting agency that is erroneously reporting this account on my reports
