Product: Debt collection

I was not supposed to billed for any of these medical debts. I am a veteran was never supposed to be billed for any of these medical bills ( there are XXXX from this company, another from another company ). The following copied from the department of veterans affairs website " XX/XX/XXXX, the U.S. Congress provided VA with authorization ( called the Mill Bill ) to pay for emergency care in non-VA facilities for veterans enrolled in the VA health care system. The benefit will pay for emergency care rendered for non-service-connected conditions for enrolled veterans who have no other source of payment for the care. However, VA will only pay to the point of medical stability. There are very strict guidelines concerning these types of claims. Veterans and their non-VA providers should be aware that these claims must be filed with the VA within XXXX days from the last day of the emergent care. " Civilian hospitals are required to notify the nearest VA hospital of an incoming veteran patient within XXXX hours from the time of visit so the VA can either make arrangements for the patient to be transported to the VA facility or to be notified that the veteran can not be transported and they can submit the billing to the VA facility. 
Each time I was taken to the emergency room whether from friend taking me or the ambulance, I told the medical person with me I was a veteran, some instances I was able to walk to the desk and check in, one time I was transported via ambulance, but that time I told the guy in the truck I am a veteran and even had on a wrist band from the VA hospital I was just leaving from ( I was in a car accident on my way home after a follow-up appt from the VA hospital in XXXX after having a XXXX and was nearly home when the car I was in was struck by a speeding vehicle, I never made it home instead I was taken to the nearest hospital in ambulance. 
So, about the bills, I never received any actual bills, instead close to a year after the car accident I received a call from a collection company and asked what bill, they gave me several bills I had in collections, I was not aware of any of them because I always thought the VA was billed initially. I explained to the collection company that I was not supposed to have been billed and they offered me to give the Department of Veterans Affairs info to pay the bills, when I called the VA they told me the bills had to have been submitted within XXXX days. I told the collection company that and they told me that I would have to pay then. They could not care less that I was not supposed to be billed. It has been years that I have been back and fourth with the hospital, collection company, other people the hospital tells me to contact. Nobody will man up and remove the bills from my credit. Instead every person I talk to, simply wants me to pay for someone else 's mistake. The staff I have spoken to are pretty rude for the most part as well, especially at the hospital. 
Please help me to find the responsible party, have them remove this, so I can get on with my life and my family. 
The billing dept from the hospital told me they did contact me via mail and provided a few date but they were not able to verify that I received their bills. They never made a phone call, the only people that contacted me was the collection company XX/XX/XXXX roughly. I called them several times since then but they have never contacted me, nor have the asked me to update my contact information when I call in, even after asking them what address and phone number they have on file.
