My 80+ year old husband loves to aggravate the scammers if they call when he doesn’t have anything else to do.
In our area the scammers often co-op local private phone numbers that list the owners name.
One time he got a call that caller ID said came from himself!
One time about 10 years ago, I was at a relatives house waiting for a ride. Everyone was asleep, including babies, so I was just sitting there doing nothing. I got a call from a scammer, so since I was bored I indulged. I would argue for a while, then ask to speak to a manager. I was on the phone with them for 45 minutes, and was up three levels in management.
