Insurances are ****s

I got an accident on the 21st of Nov 2022 then my car got towed and they told me accessor will contact me after the car has be accessed I waited untill 30 November 2022 untill I call them to follow up, what I got from them was that my car is beyond repairs it can't be fixed, which is a lie my car is not bad nor a written off, and they started telling that have I ever had an insurance for the last past five years, and the giving me 14 days to submit a prove of previous insurance, if not will not be covered my claim will be rejected n reason for my car that is nit gonna be fixed is that to fix the car will cost them a lot, but I paid n I asked them if something happens to the car will I be covered and they said yes now they coming up with stories please someone help me I am not happy at all
