When we are feeling cheeky, we have a couple of tools to manage calls like this.
I have a panic button (sounds like a smoke alarm). As soon as I realise the purpose of the pain in the butt caller, I press the button over the mouth piece. They never call back.
Hubby likes to pretend he is Guiseppe the newly arrived immigrant who cannot understand the caller, doesn't own a computer, cannot hear very well, and, even asks if it is his Mama calling. It drives the scammers crazy. They don't call back either.
We both have protective programs on all of our devices, but the occasional one slips through, usually from a mobile phone number. That is normally when we utilise our highly technical, SWAT team trained tactics.
