Same here. I had months of calls from the agency and I think only because I was extremely forceful that I would never pay them a penny that they finally backed off and told the medical provider to bill the f'ing insurance. This was all complicated by the fact that I didn't see any bill for > 9 months (while they were billing the wrong insurer).
