The Worst and Appauling service received from Discovery Insure

I currently have 3 vehicles insured with Discovery Insure. We had an incident last year Oct/Nov 2021 where my wife was driving in Midrand in extremely heavy rain and her car switched off suddenly and refuse to start. This was clearly due to the severe weather conditions. So we reported this to Discovery Insure and it took them almost 3-4 weeks to have an assessor come out. Upon his arrival he made an assumption that the headgasket was blown and rejected the claim (this was decided only on viewing and without a proper assessment). My personal mechanic confirmed that the head gasket was not damaged. So I requested the vehicle to be taken in so a proper assessment can be done, little did I know that the same person went out about another 3-4 weeks later and gave the same report. Which means they did not physically confirm that the head gasket so called was blown. The vehicle is still at the panelbeaters for almost 7-8 months with the water damage in the engine. This will now also cause more damage to internal parts which I become responsible for. This is utter rediculous and unacceptable. My agent Mr Nishan Rambali has been great has been assisting as much as he could but also limited to what he can assist with. Several emails has been sent to claims managers but ZERO responses has been received. They now said they will have to bring the vehicle back to me. This was said to take place over 10 days ago but still nothing. I do hope that the Ombudsman assists us consumers with serious issues like this
