Equifax refuses to provide me proof of how they completed an investigation that I submitted with regards to fraud. I have sent Equifax a certified letter requesting the specifics of how they investigated an account showing on my credit report with XXXX XXXX XXXX XXXX. This investigation was improperly done and it was not properly investigated an a fraudulent account. Since this investigation was improperly done I demanded by certified mail with return receipt requested proof of how they completed this identity theft investigation. Equifax is required by the FCRA to do a reasonable investigation with regards to fraud reports. Equifax has violated the FCRA and not done a reasonable fraud investigation. This account was reported as fraud yet Equifax only verified the name and address on the account, and that is not a proper investigation. I was told by a representative at Equifax that they only submitted the information through XXXX. I gave them the name and number of someone at XXXX XXXX XXXX to contact with regards to this account and they refused to contact this person. Equifax has refused to comply with my certified demand requesting that they provide proof of their proper investigation.
