to start file a complaint with your AG their AG and the FTC!!!!! they are breaking all stat & federal law.
Are they showing on you CR as a creditor (OC)? Because what they are doing is collections!
Copy all your papers!!!! the AG and FTC might want copies.
IF they are reporting as a OC I would dispute with all CRAs....then when they come back as verified....hit them with the OC letter they must answer after verifing!
I would not do anything with the CRA until the OC letter.............under normal conditions all you would need to send is case # from BK....that will not work because they were not listed on it.
Start checking out attorny that handle federal court cases!!!
