This happened to me about 5 Years ago. When I finally got finished with the "Career Change" I decided on ($90k a year to $19k a year, so worth the stress free life) I started working on my credit. Of course I had a CR about 4 pages long with countless collections, charge-offs, Judgements just a ridiculouse number of accounts default (but again so worth the stress free life).
I knew it would take YEARS to fix my credit so I started plugging away, found several account listed twice, one was even listed 4 times by same CA. Filed online disputes with TU and EX (I skipped EQ because the needed letters and didn't have the time to write letters). Within 2 months TU deleted my entire credit history, EX did the same. I called EQ and disputed over the phone, and again entire Credit history was deleted but ended up changing my birth year to 10 years earlier (Probably felt how eshausted I was and thought I had age 10 years just on that one phone call, lol) but that's fixed now as well.
It sucked because I lost really good old accounts through the process (some if still there would be 18 yrs old), but I just kept my mouth shut and lived with it. I tryed calling my old creditors to have them report the good ones again but I haven't had success. I acepted it and now 5 years later, I had a few Judgments from 2 years ago pop-up (didn't know SOL rules and didn't show up to court), but I'm sitting on a FICO that ranges from 620-688 depending on the day of the week

Sorry if I hijacked your thread, but my point was I haven't had sucess having old good TL's added back to CR........
