Bad experience with the Salvage Department

My vehicle insurance claim was rejected and the car was sent back to me, but weeks after that I learnt that my claim was reopened and it was approved. according to them the car was a write off of which they had to just payoff the car but it have being weeks just because I want an option to buy it back as I already fixed the car. I spoke Sonia (Salvage department) now for weeks now but is just back and forth and these is still my issues There is no compensation in all the repair that is done to the car. Zero guarantee on the possibility of buying my car back. They want to collect the car as it is and I have to follow the normal biding process whilst they were not involved on the repair of the vehicle, so who must benefit from the repair that is already done to the car? Their customer service still have a massive room of improvement, no update on the progress of the claim and I was the one always calling to get an update. salvage team even worse, arrogant approach and easy to get angry (there is recordings on these).
