Hello, I have disputed an account with Experian to validate the accuracy, In return they sent me a letter stating they have validated the information, I sent a letter to XXXX XXXX via Certified mail requesting validation which no response was ever sent back. I contacted Experian again via mail and they refuse to investigate the account stating they have already validated. I have made multiple attempts to contact XXXX with no response. I have attached the following communication between Experian and XXXX as proof.
