What creditors only go through Experian??? My credit file got mixed in with someone else's. Because of this Experian deleted a good portion of my accounts. All good accounts of course. But since I had so many accounts this actually hurt my score. Now all these accounts have dropped off it was increased my score quite a bit.
Though this is on another forum, I've found it useful in the past. It's the Who Pulled My Credit forum on yahoo. They listed this precise info. http://finance.groups.yahoo.com/group/whopulledmycredit/
