Several years ago Trans Union dropped my credit score for no apparent reason. Today my Experian, Equifax, and FICO scores are 150+ points higher. TU is being very difficult to get a proper revision. How do I get them to re-score my credit?
There is not much you can do about a recalcitrant credit agency. The only thing you can do is get your credit reports (free from the link below), scrutinize the TransUnion data, and file a dispute if there are any inaccuracies.
