Totally correct. Your Crewing guys are well out of line.
If they're doing this as a matter of course to everyone, either:
1) Turn your phones off until the start of SB duty. (Easiest option)
Or..
2) Tell them they've disturbed your rest and you'll now be unavailable until you've completed another rest period. (Ballsy option!)
It may not make you popular, but rules are there for a reason. With a bit of luck the penny will drop and things will change.
