Bad Customer service

I had a vehicle from my fathers estate in KZN that had been involved in an accident . The insurance company PSG underwritten by Santam were informed. It took almost 8 months before any work started by status panel beaters in KZN, this was only the beginning of my nightmare. Firstly the repair work that was quoted on by the status panel beaters was not done , I informed PSG of this and a MR Smith from Santam . I then took the vehicle to another Panel beater who was informed that there was not adequate funding so they could only repair some of the damages, at this stage the vehicle was driveable but had some serious stability issues. I took the vehicle to Chevrolet in Scottsborough who informed me that the chassis needed straightening and stabiliser bar needed to be replaced. I informed the both insurance companies who informed me sorry we have paid the panel beater concerned and it was no longer their problem, should I have a problem with this I could do what ever I like. I believe that an insurance company should where possible repair the vehicle as it was before the accident.
