Hollard insurance claim complaint

On the 20th of February 2019 I was involved in an accident where my vehicle was driven into by a truck.After recovering from my injuries I contacted my insurer( Hollard- who covers me for accidental write off and vehicle theft)to inform them of the accident as well as to process a claim.Hollard sent an assessor to inspect the damage on the 26th of March on the day of assessment the gentleman that came informed me that he seemed the car as a write off but however his Supervisor (who was absent )would make the final decision.On the 10th of April 2019 I received an email informing that my was rejected, as the car was not a write off. I then got two other assessors to verify the condition of car and they also confirmed that it was a write off. I am so appalled at the incidents that have occurred as I thought Hollard would be one of the best insurers for me.The vehicle was returned to me on the 12th of July 2019 with more damages on there than what was initially on it.I have honestlly tried my best to request that they get another opinion with no avail.I was informed that this would be one of the platforms that would assist me in getting my compliant heard.I used my vehicle to earn an income and this has left me at a financial disadvantage.
