They don't want to repair, but rip me off

I have been insured with Momentum for 3yrs with no claim. I paid 900+ premiums monthly on a 2014 ford fiesta. I had an accident on the 12th April 2023 and claimed. Zanele Mahlangu was nominated as my claim consultant. She contacted me on the 19th April 2023 and advised me that the car is a write-off due to the quotation being more than 70% of the retail value. She said they only of fix is its less than 70%. Today the 24th April 2023 i asked her to send me the quotation done by an assessor, of which she did. The assessment was done on my car and the quotation was less than 70% of the retail value, which contradicted what she said. I called momentum again for clarity, the other lady advised me that the system says 70%, but they it is actually 50-65% and another thing is that they dont want to inconvenience me by taking long to repair or finding the car parts "like what the f**k is that". I'm already inconvenienced, just fix the damn car". But nah, she went to manager to ask about the 70% and when she came back to the phone, she said its actually 40-70% as if they will fix when its 80%. I then asked to speak to the manager. I spoke to somebody by the name Tiane, that manager was so arrogant and didn't even want to understand my frustrations. He even compared my situation with his as if he is paying.my premiums. I don't even know if hw has RE with that arrogance and stupidity. After all those calls i went to my policy schedule and it states that they will treat my car if damages are less that 70% of my retail value. Currently my car damages are less than 70% and they refuse to repair. I wamt them to repair my car so i can insure it again, not their stupid settlement. If they don't want to repair they should give me the repair amount on the quotation and my car so i can fix it with professionals and insure it again.
