Hi Dollie, and welcome.
Sounds like this woman is not playing with a full deck, JW or no. I think you did the right think in writing the WT Society, but I agree with the above post. I would contact the local congregation and let them know your experience. With your other scam experience, you might want to contact the Better Business Bureau.
I think the main thing that people want to do with this is to 1) Stop the Behavior 2) Let someone in power know and 3) Stop this from happening to anyone again.
You've already taken the first step. I am an ex-JW and have no apologies for them, but I can say they, in represented the society, would never say the things that you heard this person say.
Good luck. Hope you visit here often and let us know what happens. You don't need that kind of trash in your life.
