difficult claim process with Hollard insurance, after 7 years of no claim history

My car had an accident in January, today is 15 May, the repairs are not done and Eric Fletcher, the assessor appointed by Hollard, has spent the good 4 months questioning what he can do best to cover least damages as possible. My Mercedes returned half done, with electronic issues i have never seen before and cracked camera. i have been never had a car claim in 7 years and this is the service i get.
