Even if the case is settled at 50/50 you wouldn't loss all your no-claims, only half. This happened to me when I had 5 years NCB and Admiral halved it to 2.5 years, and than rounded it down to 2 years.
Hope you get it sorted, its annoying enough dealing with just your own insurance company , but these days with all the middle men involved wanting to make a quick £££ its really hard to work out whats going on with your claim or whos actually on your side
