Mutual treasure is fraud. I am 69 years old, and I was cheated of money for no reason?

What is mutual treasure? I've never heard of it. I'm afraid it's specially used to deceive the elderly, especially people your age, who are the easiest to be deceived. You can't use a smartphone, can you? Even if you don't have the ability to distinguish, it is puzzling to you, but it may be clear to others. You must believe the liar's sweet words, and cheating on each other is similar. If the evidence is conclusive, you can call the police. If you don't have much money, spend it on courses!
