You'll want to follow the HIPAA process outlined on several threads TO THE LETTER. Essentially:
** DO NOT COMMUNICATE WITH THE CA **
1. Send Pre-HIPAA letter to CRAs reporting the CO.
2. After validation, send HIPAA letter to OC with proper insert (usually if you're paying it, #1.)
3. Wait for deletion. If the check has cleared and you haven't seen your CO deleted within 30 days, post here again.
