Terrible Service

Over 2 months ago a Hollard client hit my car from behind. Firstly I waited nearly a month for someone to contact me in regards to repairs etc. Once I had sent through all the quotes etc I waited Nearly 3 weeks for a response. Commrisk's assessor had decided that he will talk the panel beaters down to give me an offer below the lowest quote obtained. I have been arguing for over 2 weeks for the offer to be redone. I was not in the wrong, I did not cause the accident and I am getting ignored, made wait and being low balled. I believe I should have a choice of where to take my car, and being paid out less than the lowest quote is unacceptable.
