I'm sorry to hear about your accident.
I suggest getting a lawyer.
I was hit by truck last year. I wanted to do the right thing and just get my bike replaced. I tried working with the company that the guy who hit me worked for but they were complete a((holes. I called, faxed, for 3 weeks with these nitwits. All I wanted was to have my bike replaced. When they found out how much my carbon frame bike would cost to replace I think the were shocked. I guess they thought I was riding a Huffy.
I hired a lawyer that is a cyclist. He has handled several bike cases. I ended up getting more than I had originally asked for and it cost the a**holes twice as much as it would have if they would have settled in the beginning.
Keep a record of every event, encounter, phone call, messages you left, calls that were not returned, report, fax, email, etc. Dates, times. A month from now it will be difficult to remember what happened when.
Get a lawyer and let him/her take care of it. I wasted a lot of time at work and home.
