We are lucky with my 87 year old Mom who is a widow. Even though she lives alone and is still bright and alert and can take care of most of her own banking, etc, one or more of my brothers and I check up on her daily. She gets constant reminders to Just say "No." If she has any questions about anything, the oldest of my younger brothers has power of attorney and helps with them. God Bless your Mom and may this never happen to her, again. :) yes they will pay for their rotten actions as cjmomma wrote.
