PLEASE NOTE:
You don't have to put up with ANY of this. There are laws in most states that can be invoked....in your case, harassment and stalking.
Congregation elders are mental midgets. The Watchtower Society sent out several letters to Body of Elders admitting they will distance themselves from elders if they're hit with a lawsuit.
Go to a lawyer and get them to write a letter stating they will sue the local congregation, as well as the Society if you are contacted ONE more time. (or make a fake one yourself with a fake letterhead)
They will crap their pants and disappear.
I never understand why so many people put up with elders. They are NOBODY! Absolute zeros.
You could also do what I did .....and I was a former long time elder.......if they knock on my door, I come to the door with a gun. You'd be amazed how quickly they leave.
