Ambulance company failed to bill my insurance 4 years ago and reported me to the...

...credit bureaus. Need help!? I was in an accident nearly 4 years ago and was taken to the hospital via ambulance. As I understand it, they took my information then and they claim they submitted the bill to my insurance company. I figured everything was all set but have recently been getting collection calls for nearly $1000 and this has shown up on my credit reports (which unfortunately I have only begun to monitor lately). I have been in contact with my insurance company (who tells me I owe nothing in this situation because it should have been covered) and they say they received nothing from the ambulance company until the end of Feb 08! The ambulance company insists they did nothing wrong and refuse to take this mark off my credit report even when they are paid by my insurance.

Do I have any recourse to have this removed from my credit reports? I need help! Thanks!
