I've seen some scams in my day too. One that i remember vividly is when these scammers called my hubs to tell him about " unusual activity in your visa"
Hubs: which "visa"
Scammer: sir i need your social security number before i can verify that
Well it didn't go over very well. He called the bank you to let them know, they were already aware of this one, but You can imagine how perhaps an elderly person might react or anyone Who can't advocate well for themselves
Oh yes that one. Wow how horrible!
