My 89-year-old mom, who is of sound mind, has lost most of her money to a scam. She refuses to believe it and thinks that with "one last payment" she will get her money back. She doesn't believe my sister and me when we tell her this is a scam and show her stories about the scammer. How can we maintain her dignity and privacy in this moment yet extract her from this brainwashing???? Help!! (My sister and I live 500 miles away).
