Welcome
I sent several letters to Bethel.
The innocent ones they might answer you.
When criticizing them or suggesting reform they either don't answer or tell the CO to answer you directly or through the elders.
Then you are on their radar as someone who has doubts. They will try to readjust you. If that doesn't work over a period of time they leave you alone if you are lucky or they disfellowship you for apostasy (thats what they did in my case).
