crikey, good luck in sorting it all out
i am with ensign too, and they werent the best when dealing with my write off. i also tried to buy back the salvage but they didnt even acknowledge that as an option
they were quite slow too, but they came good in the end increasing their offer from £3500 to £5000.
have you called them to discuss the situation? it was only when i spoke to a human (rather than writing / emailing) that the ball got rolling
oh and if i remember correctly, they cant scrap your car within 21 days of the claim? but they can after that if you dont specify otherwise
