It worked - sort of!!! LOL
So around Apr. 19th I sent off a 4 page letter to Experian, disputing over half the items on my credit report that were my dad's and not mine, as well as some personal information they had screwed up (his birthdate on my report, his SSN on mine, old address, employment, etc). Hoping for the best, but expecting the worst, I waited.
Well yesterday, I recieved an updated copy of my report from the disputes department, and they had removed all the disputed credit accounts!! Hooray!! For some reason (they said security), they didn't include birthday, SSN, or employment information, which irks me, since I can't check it to see if it's correct. They won't list the SSN when I bought online either, so I have no way of knowing whether it's been corrected or not - will have to call and check on that. But getting all those accounts that were not mine off is a *huge* relief...much better for my credit. :-)
