I was once volunteering for an elderly man whose wife had just died. I was working with a group of Catholics to care for people like him...to get him on his feet and get the service s he needed to him.
I walked his dog every day for him and in the course of being there, I realized he was getting a lot of packages full of worthless stuff constantly in the mail. For example, he got one thousand pen marked “Say No to Drugs!”
Upon questioning, I came to understand that every evening he got multiple calls offering him free stuff. But every time they took his credit card number and large charges showed up on his card. He was being scammed and by the time I figured it out, his savings account was nearly drained!
He would not cooperate in stopping it. I had no power to make him. He went totally broke with me watching. He then moved into ghetto housing and had to put his dog down.
So sad. He probably enjoyed talking to the scammers at first. When he figured it out, he was probably too polite to tell them to take a hike.
Such a sad story. My late FIL was scammed a few times while he was in his 80s.
