I would like to share my experience with you, , 10 years ago I have the same situation like you, but it is a Proton saga.
I wrote to the insurance company, staying that the a pillar is crooked and the only way is to re weld with another a pillar, I said you can do what ever you can to salvage the car, but after that I will bring it to puspakom for inspection.If fall then I will claim total loss from your company, however I am will to accept certain amountof compensation as total loss.
Then they accept and I get the money instead of repairing the car.
You must write to them yourself.
