buffalosrfree, I really like that!
I found "NO" works well. Like, sister, can we visit you on Monday for a shepherding call? No, that's not convenient! When would be convenient then? I'll let you know. End of conversation. Repeat as often as necessary.
If they call unannounced, say, I'm sorry it's not convenient right now.
Usually they'll feel fine because they made the effort. Sooner or later they'll leave you alone.
