Cold Shoulder

I refer to Claim Number ********** . I was invloved in accident and put a claim with my insurance. Given the options of panel beaters I chose Auto Magic on Flemming Street in Meadowdale. I took the car in for assessment and a few days later I was then sent a quotation based on the pictures taken during the assessment. The vehicle was delivered to the panel beater on the 3rd of August 2018. I was advised by the panel beater that they may need further authorization if they discover more damage after stripping. A month later I recieved an sms from the panel beater informing me that they were waiting for authorization from my insurer for additional work and parts required. I did not hear anything from either the insurer or the panel beater. I called Auto Magic on the 17th of September 2018 to find how far they were with the repair. I was informed by Auto Magic that this claim had been removed from their system and that my insurer had written off the vehicle. I called Hollard and the person I spoke to was surprised that I had not been informed of the writeoff. She said that this matter had to be dealt with by someone who was currently not available at the and offered to pass my details to that person to call me back. I did not recieve that call back. I called again after a few days and spoke to somebody that had no idea about my claim, the writeoff of the vehicle and the whereabouts of the vehicle. Again I was told there is a special person that has to deal with issue and that person was not available to take my call and would call me back. That call has not happened so far. I am very frustrated and worried that it has been over a month no one knows whats happening with my claim and my car's whereabouts. I have been sent from pillar to post by call center agents who either have no clue what they are doing or just don't care. Can somebody please advise me on what next I can do to get some progress on getting my car back.
