Don't just give in mate, to me and probably to you, this is a big deal with a big amount of money involved, in terms of your car and the money it will cost you on your insurance going up, if you have legal cover with your insurer, don't ask them, TELL them that you want to take this to court as it was not your fault, you'll have to put in a lot of time, effort and phone calls to make it happen, but it won't at all if you don't get on the case.
Don't give up, what have you got to lose?
