Advise your insurance company that you do not accept the car being written off and you want it repairing thus returning you into the same state you were in prior to the accident (which the insurer has an obligation to you for). I have done this successfully twice now on behalf of family members. Stick to your guns and they will huff and puff but should back down and give you what you want. Also this will avoid teh car being recorded as a total loss
