I would absolutely call the insurance company and the creditor to get an accurate understanding of what is going on. I would also dispute with all three CB, that tends to get them to take at least a cursory look.

If those don't work file a complaint with the CFPB. We have done that three times and every time the other party dropped anything negative from our reports.
