Most unhappy

I had a third party claim with Outsurance as I did not have insurance on my vehicle. The person handling the claim, in my opinion, did not do due diligence. Even though their client admitted being in the wrong which I have on an email I received, they still claimed 30% of her costs from me. My vehicle was written off by Outsurance without an assessor checking the vehicle and no quotations were asked for. Now I have to buy a new car. How I am supposed to do that with the measely amount paid out I don't know. Outsurance will definately not be contacted for coverage of my new vehicle.
