I was disfellowshipped in absentia.....
I had moved to another city and had not been to a meeting in a couple of years and they still hunted me down like a wild animal. The elders in my original congregation kept sending me certified letters that I refused to sign for. They would leave messages on my phone of dates and times of committee meetings that they said they would be in attendance of whether I showed or not. I heard through the grape vine that it went through three separate committees and two congregations before they gave up and just read the announcement that I was Df'ed. They then hunted down my elderly parent's congregation, yet in another city to get the news to me through my parents that I had gotten the axe.
....And all I wanted was just to be left alone. Which I eventually achieved.
