no response to 3rd party claim

Legacy administrated by hollard- commercial...their client bumped into Me 19/9/2015...due to damage less than access,the claim was as 3rd party claim,I was send around for almost 2 months now, 4 quotes where send after I must agree to 2nd hand parts... Which I did...just to get it done, I cominicated with their 3rd party lwyers which agree that I'm entitled to my vehicle to be fixed,according to the 3rd party claim lawyers they did communicate to legacy and informed them about claim,according to the lawyers they (legacy) did not come back to them after lots of emails etc...I personally phoned the person that is the client of legacy according to him his vehicle has already been fixed...it's not even my fault their client bumped into Me,now at my own cost I appointed a lawyer and sent a demand letter,stil nothing heard from them...why is it necessary for a 3rd party to go to this extremes,what about the consumer that just gave up and fix on his own cost? That is not service and the consumer must be protected,I wil not fix it at my cost,I want only what's right
