You could write NY and ask them why the congregation isn't following the 'do not call list'. Isn't the 'do not call' a rule of sorts that comes down from the gb/org? if it is then those jw's are running a head of the org and not listening to mother! I wonder if you named names if those people would get marked or something?
I have written NY in years past and the letter(s) do actually make their way back to the local cong/ elders and actions was taken against a jw, that was my experience anyway.
Or write them back and bring up the pedophile problem, doctrinal issues, court cases, etc.... and that is why you are not coming back.
Or, just file it all in the recycle bin and feel bad for their sorry life in the jw's.
