So I've been helping my daughter repair her credit since her divorce. Experian supposedly researched the discrepancies, especially with a Capital One account that she doesn't remember having. Her ex was very good at getting credit, maxing it out and not paying. She seems to think this is what happened. (The account is listed in her name only). He had also at one time ran up an E-bay bill in her name which was successfully disputed.
Under FACTA, as I read it, we can contact the original creditor.
