What you should do is send or hand deliver a copy of the letter from the OC to the Court House and tell them they have been inaccurately reporting information to the 3 CBRs, and they they are in violation of your civil rights as outlined in the FCRA.
You can then ask the court house who reports to the CBRs for them and send them a copy of the OC's letter, too.
And then dispute with all three CRAs the next day, via fax.
