I like to share stuff like this with whoever. Anything we can do to defeat the scammers is a good thing. I have caller ID, if I don't recognize the number, I don't pickup. Usually then, the "caller" doesn't leave a message. And I keep my phone on mute, so never hear a ring.
The rule is to never talk to anyone you don't know. And if it's your "bank" or "credit card company", my advice is to hang up and then call your bank or card company and find out if they did in fact call you.
Be wise. Contrive a plan and stick to it. Never talk to strangers. Don't speak softly, just carry a big stick. Don't sign on the dotted line until you read the fine print.
