Third Party Claim

On the 28 August 2015 i witnessed a lady involved in a smash and grab incident. Logic suggested to stop and help her. She parked her car on the yellow lane with someone else parked behind her. My car had its hazards on in SLOW moving traffic on the side of the road when your client rammed my car from behind trying to beat a truck to catch a gap. Before she rammed my car people were screaming at her to stop but she didnt look in front of her but rather at the truck next to her. Finally after a long time i get an offer letter stating that you will only pay for 50% of the damages despite having to explain what had happened and also when your client called me she advised that she was at fault. How can i fix my car with 50% and then for your consultant to tell me that i was partly to blame for parking my car on the side of the road as though i parked it in the middle of the road. Then when i said to her your client will then need to cover the other half of the damages i was told not to make any contact with your client. How is it not your client's fault for looking right instead of straight whilst driving forward???? Your guys are pathetic !!! Just FIX MY CAR !!!!
