I just noticed something this last month. I disputed 2 of my wife's collection accounts that had wrong info. I disputed them with a CRRR to CSC on 10/5. They didn't put them in 'dispute status' until 10/20. They deleted both on 11/4. Before the dispute and during the dispute there was only a 2 point score change I attributed to lower utilization updates on her report. It wasn't until the 2 tradelines were deleted that there was a 31 point increase the same day. So I don't think that CSC 'in disputes' affect EQ FICO. I used Credit Watch with daily pulls to monitor the reports. Anyone out there have the same experience?
My score has NEVER changed when I put items in dispute. I thought I was the only one that wasn't so lucky.
