On Friday XXXX XXXX I contacted equifax to dispute a duplicate charge from XXXX. I explained that there are XXXX accounts listed, XXXX closed and XXXX open with a balance of XXXX. I explained that the account was closed in XX/XX/XXXX and this account is a duplicate. Equifax reported on XXXX/XXXX/XXXX that they had completed the investigation and that they contacted XXXX and " the balance is being reported correctly ''. Equifax then changed the date of last reporting on my credit report to be XXXX/XXXX/XXXX. On XX/XX/XXXX I contacted XXXX and they stated that they have never been contacted by equifax and that I have no open accounts. They stated that there are no open accounts and They mailed me a paid in full letter. I have tried multiple times to file another dispute with equifax online, but their system states that the info I 'm inputting is not valid and it will not allow me sign in. This duplicate account has been on my credit report since XX/XX/XXXX and is currently prohibiting my ability to obtain a mortgage.
