The issue is both with carriers to enable the feature and BlackBerry on how the OS handles blocking. Not all carriers support it at this time.
However, the OS itself currently won't solve the problem sought after in this thread. Even if enabled, 10.3.x only allows blocking of all incoming and/or all outgoing calls. It does not have the ability to block individual numbers.
It's unknown why true individual call blocking isn't a feature in BB10 at this time.
