I have not read the entire thread but what insurance company are you using ?

In all my experieneds, the shop already has a # by the time the adjuster arrived. What ~adjustments~ that need to be agreed upon, it is usually done right on the spot with the shop. The adjuster generally has called me with a update on how much $ when he is at the shop or just the same day, depending on how mobile/appoitments he has.

I've never had such a delay.
