Reminds me of a situation that arose about six months after I stopped attending in 2006. Not a single call to check where I was, how I was doing, etc., in that six month period. Until...
I received a phone call from the PO, (one of maybe two times ever he called my cell), and I let it go to VM. I checked the VM, and it said something to the effect of, "the brothers heard about some things you are doing and wanted to speak with you...". This was an obvious invitation to a JC, supposedly because I was living with my girlfriend at the time. I blew the call off.
Then three weeks later I receive a second call from this same asshat. I let it go to VM again. This time something to the effect of "we know where you live, you live in (an improperly pronounced town), and we want to send your records to the congregation there". This was another pitiful attempt to get me to confess something to them. I ignored them this second time and never heard back.
The simplest and most effective thing you can do is simply ignore them. That takes all of their power away, and not a goddamn thing they can do about it.
