For those who want to know:
I had a "4 " yr old collection with Credit Management (Comcast). Typical of Comcast, they claimed that I had a balance due when I did not and sent it to collections. I ignored it until past SOL. I had Comcast Internet service, which I cancelled for AT&T. I called AT&T who confirmed that I opened my account in August 2010. I finally got around to calling Comcast today and the woman confirmed that my last payment was in September 2010 (sounds like a final bill to me!). Their automated system says "balance is $0". The records were so old that they couldn't pull up what I owed them for so they "opened a ticket" to get those records. In the meantime, I called Credit Management. I spoke with the supervisor an explained that I didn't owe Comcast, but that was besides the point. I explained that I had disputed their listing on the 3 bureaus multiple times and each time it came back verified. I further pointed out that they verified a DOFD of 9/2011 each time. That since Comcast's last payment was a year before, their verification amounted to willful non-compliance. He cheerfully agreed to delete the TL!
I then, based on information I read here, called IC Systems explaining my dispute with their OC (CareSpot - an urgent care clinic). The woman was empathetic. I said that I have a win-win for us....that I would simply pay the $51.50 if they would delete it from my CRs. She agreed, sent a letter confirming this and said that they update every Monday, so it should be gone shortly.
I have only AMCOL left! I am looking forward to being collection free again! YEA! 
Starting Score: 472
Congratulations on your success, way to take the fight to them! 
Thanks for that info. The AMCOL is only $95. I have no problem with PIF, I just want deletion.
