Discovery Insure NOT client focused

I drive a Kia Seltos 2021 model and on Saturday, 21 May 2022 I was involved in a collision. The car was taken away and a claim was submitted. The Monday I got a call from the assessor saying that he doesn't have that vehicle under my name. So when I called Discovery, they submitted a claim against my previous vehicle because the person who we spoke to in October 2021 to update my insurance, never updated it on the system, even though I have the email confirming my vehicle change. I was then told I would need to pay in the difference in premium for the months passed (old vehicle vs new vehicle). That claim on the old vehicle then needed to be closed and a new claim was submitted. (so now it shows two claims on my profile) The assessor concluded his assessment and then another assessor was assigned who then opted for my vehicle (7 months old at the time) to be repaired. When questioning this and disputing this with Discovery, I was told by Lebogang Makgato that their 'write off starts at 65% and my vehicle came in at 50%'. I was baffled that this company would rather play around with a 15% technicality than doing what's in their client's best interest, which to me seemed like replacing the 7 month old vehicle. Will this vehicle be in the same condition as the 7 month vehicle I had? I doubt it. Today is 16 July and my vehicle is still standing at the panelbeaters from which I received an update that THEY ARE STRUGGLING TO GET THE PARTS! OFCOURSE YOU WOULD! The car is not even a year old yet and with every passing week and month, my car's value is dropping! I WANT to dispute this and I want my car to be replaced! NO ONE is coming back to me and I am 100% NOT receiving any form of client service SINCE the day of my accident.
