There is a option that might help. Go change your password on battle.net for the affected account(s). Apparently there are cases where your account and the b.net database can get..."out of sync" for lack of a better description. Changing your password forces things to sync again and may resolve this. I'll admit I heard of this originally when I was unable to get one of my Diablo3 accounts to realize it was past the end of the probationary/trial period and open up full access to trade/bank/etc. Doing this resolved it. I have no idea if it'll work for you but it's worth a shot.
Good luck!
