Third-Party Claim Nightmare!!!

I initiated a third-party claim through Outsurance as my vehicle was involved in a minor accident that was undeniably their clients fault. I provided a quotation for the repair costing R37000. After weeks of poor correspondence and having to continually follow up, they said their panelbeater could do the repair for R11700 (less than a third of the quotation ???). I then took my vehicle to their prescribed panelbeater with Outsurances assessment/offer in hand and they then assessed the vehicle and quoted me R60000 to repair the vehicle. I provided this quotation back to Outsurance, who then made a new shocking offer of R29000 (!!!) The panelbeater highlighted that the Outsurance assessor/assessment had left off several required parts and they could not the carry out the repair for R29000. The liability officer that I am dealing with at Outsurance does not respond to any of my emails despite requesting that he acknowledge receipt each time. He, nor his supervisor, have ever returned one of my phone calls to date. When I have nagged a response out of him, he always provides me with the bear minimum response and never responds to any additional questions raised in my emails. It has been over 6 weeks since I submitted my claim and my car still remains unrepaired. Outsurance seemingly do not care about third party claims and delay the process in a most unprofessional manner. They also clearly do not care for the quality of my vehicles repair job. It is by far the worst service I have ever received and thus worthy of my very first HelloPeter-based complaint. It is so shortsighted to deal with people in this manner as I will now never support Outsurance and I have nothing good to say about them. I have lost so much time through wasted emails and phone calls and have been caused a significant amount of stress through the shocking service I have received. And despite the fact that their client negligently smashed into the back of my vehicle, I still sit with a damaged vehicle with no end in sight.
