You handled that very well- reasonable, logic and a legally valid concern expressed.
I record my conversations with JWs then write a letter to them to documenting the conversation. In the letter, quote them exactly and explain exactly what is wrong with their conduct .
Send the letter to the congregation secretary and demand a reply with their remedy to the situation.
Dubs are just witless little drones and shunning is their one and only chance to feel powerful. The congregation created the insanity so demand that they fix it. Bury them with paperwork resulting from their vicious hateful policies.
Shunning looks petty and ridiculous in print (and may even violate a legal agreement)
The real value of the letter is that it is a document upon which legal action can be pursued and will be viewed as such by the boe.
It´s actually fun to dump the mess right back in the secretaries lap - good luck
