<human>: Give me a shortened version of the text

A little over a month ago, I had a seizure at my workplace. I have epilepsy, and my coworkers know about it and were told by me not to call 911. Since I am a contract worker, they don't cover me under their health insurance and since I have a preexisting condition, i have not been fighting for months through the bureaucracy to get PCIP (insurance specifically for preexisting conditions), which does not kick in until December. 

Anyway, I had the seizure, coworkers called 911, I refused service, they strapped me to a gurney anyway, I refused service again in the ambulance telling him that I couldn't pay the bill due to being uninsured, the paramedic said not to worry about the bill, wheeled me out of the ambulance once we arrived at the hospital, and I was never admitted to the hospital. 

I now have a bill for $1400, and when I called the billing dept., the woman said that I had to write a letter to the company and to make sure include everything in that story, specifically the back and forth in the ambulance. Is she walking me into a trap? Are their certain things that that letter would provide to show financial culpability?
<bot>: What's the best letter to write to an ambulance company to dispute charges for services that you refused twice because they were medically unnecessary and financially burdensome?
