Just had to share:
I started with the pre-HIPAA, as WhyChat says, just around a month ago, after having foolishly sent a PFD offer (that was obviously rejected). Should have done it sooner - wish I had known sooner. There was only one collection I was dealing with, and it was reporting as a current/open, so was really hitting my scores pretty bad.
TU responded within about 4-5 days with a deletion.
Got my EQ and EX responses today - both deleted.
Thank you, WhyChat, I would have never known I could even try this without all of your information.
