Sorry to dismay, but this was part of an arrangement set in place before I left.
Elders are supposed to visit exJW's annually to invite them back.
It should be enough to politely tell them: "My opinion is the same and I still have no intention of going back, thank you" - followed by shutting the door.
Alternatively you have an annual shot at counter-witnessing, unless they get to the point where they actually give up on you as a lost cause (more usually in the case of rampant apostacism).
I've never had such a visit, and I've been out over two years now.
(Lucky bugger, huh? )
