worst treatment in time of need

my car was in involved in an accident, unfortunately 8 months from another accident it had had. so the insurance is busy investigating the circumstances around its happenings. obviously, as a family we are upset that the vehicle has been in an accident yet again in such a short space of time and the last thing we need is the insurance making us feel worse about it. A person appointed to investigate the accident Riaz Mahommed has been absolutely rude and unbearable as a person to deal with. He keeps making subtle accusations in that the circumstances of the accident as reported are false. He has absolutely no grounds for these accusations as we had given him the phone number for the break-down vehicle (a stranger we had no prior contact with) who took the car and confirmed the same information we had given Riaz. He further gives us the wrong forms to be sent to the cellphone company (sends MTN forms instead of Vodacom) to confirm cellphone records. For this mistake he blames me and says the claim will be suspended in 30 days. I have never been so horribly treated by an insurance company. I am really really disappointed.
