<prompt> Human: Last winter I was involved in a single car crash on an icy road. The angle of the crash and how I impacted with the airbag left me with pretty severe concussion. In the aftermath of the crash I called 911, police showed up almost immediately. The timeline on all of this is very hazy but I believe after about a 30 minutes I heard one of the officers in a very agitated call on his radio about the ambulance being lost and about 10 minutes after that I started vomitting so the police drove me to the hospital. I have decent coverage so the hospital bills were paid and I had some additional overage charges which werent that big of a deal. So I very hi nearly thought one of my friends was joking with me when I got a call from the ambulance company demanding an insurance address where they send thier bill for services. This lady was very rude so when I figured out what exactly she was talking about I just hung up on her. About two weeks went by and I got another call from a much more polite person and when I explained Id never been in one of thier ambulances, she promised to look into it and get back to me. Mind you this was a company I had no idea even existed so I had no way to follow up. When they never called back I figured that was the end of it.At lease until last week when I got a call from a collections agency saying that I owed 1734 for medical,services received on the date of my accident. It didnt even click this was about the ambulance thing again and I explained that my insurance covered thier costs and I paid the overages and could provide all documents to show this. The collections agent then accused me of fucking him around and that he didnt take kindly to that shit. I asked him where he would like to send the documents and he hung up. Next day it was a differnt guy from the same agency who promised to fuck your credit if I talked bullshit about documents again. I did finally get him to tell me that this was about the ambulance ride and not the hospital services before I hung up on him.Any further calls from this number Ive let go to voicemail and they have not left any messages. My questions:1. This sounds crazy but how do I prove I was never on the ambulance?2. The mistake is obviously with the ambulance company, but what responsibility do they have in this now?3. Can collections really affect my credit on this?4. Is threating me like this legal?Thank you very much in advance.  <response>: The debt seems invalid because you did not ride in the ambulance.
