3rd Party claim with HCV underwriting managers

I was hit by a truck insured with HCV whilst stationary at a robot. Complaint is about the poor work ethic of its staff, in particular the legal manager who never seems to be there to take your calls. Incident happened in September and I am busy with a tug of war as they are trying to write my vehicle off and I am refusing. The most frustrating thing is the feedback and communication. Next step is the Ombudsman
