I have fun with them. I answer all "unknown caller" or "potential spam" calls. I answer as a fictional business.
"Customer service department! How may I direct your call?"
"Memorial Garden Cemetery. Grounds keeper. Jonathan speaking. How may I help you?"
Confuses the hell out of them. Since I started doing that, Robo calls have fallen off dramatically. I think it gets your number removed from their call lists.
Kind of disappointed as it's fun to cook up amusing scenarios.
My favorite exchange:
Me- "Malibu Express. Now offering clothing optional cruise to Catalina Island. Reservation desk."
Hesitate Female voice- "Sorry I think I got the wrong number."
Me- " That's okay. Maybe we'll see you next time."
I doubt I'll be hearing from them again.
My favorite answering method is: FBI. Which agent would you like to speak with?
