Bad service and not prepared to listen to our side of the story

My vehicle was involved in a hit and run, my insurer is Alexander Forbes, they were contacted regarding the incident, and we were told to take the vehicle for quotes to thier service provider. Anyway quote done and excepted, vehicle booked in with Renew It Randburg. They had it for a month, when I collected the vehicle there was not water in the radiator bottle, I had to ask for water to fill it before I left, my fuel gauge was no longer working, when I questioned it, they had said the fuse blew and they had to change it, but still it didn't fix the problem, the vehicle had problems starting, the battery was only a year old, but anyway they replaced it with no issues, for that I was thankful. They still could explain the fuel gauge problem, I complained about my suspension they were supposed to call me when they had a courtesy car, I'm still waiting for that to happen. Then my aircon was not working so I took it to Bosch to regas, after all that found that the cords were cut and they had to solder them up, after which it still didn't work because the compressor was seaced. Since recieved the vehicle back the engine was loud and just not running right, Alexander Forbes was notified and they arranged for the vehicle to be taken to Bosch where my vehicle gets serviced, where it was assessed and a report sent to Alexander Forbes, where according to them had to send an assessor to assess the vehicle according to the report from Bosch. According to the assessor the damages is wear and tear, so after its been standing for a month at Renew It , we get the vehicle back and it stops working and they say it's wear and tear, my vehicle for its age is not leaking oil, didn't use water, serviced on time and is in mint condition, if anything goes wrong I repair immediately as not to allow my vehicle to breakdown on me, as most of my day is spent in my vehicle. I have lost so much of business due to my vehicle not running, and Alexander Forbes refused to take on this with Renew It. This has been an ongoing issue for the past two months and neither Alexander Forbes or its service provider Renew It has helped with regards to my vehicle.
