I don't get angry when telemarketers and scammers call. I get creative. Recently I received a call at work to extend my car warranty, a common scam. It went a little something like this...
Scammer lady: Hello, would you like to extend your vehicle's warranty with us today?
Me: (In Eastern Europeanish accent) I am Jebediah Moreskavitch. I need warranty on vehicle.
Her: Good. I can help you with that. What make and model is your vehicle?
Me: He Ox. He 12 years old.
Her: Is that a car? What are you saying?
Me: No car. It is Ox. You can hear me, no?
Her: Sir, do you have a car or not?
Me: You say you give me warranty on vehicle, no? Vehicle is Ox. Give me warranty or I sue you for being liar.
(Click. She hangs up.)
Warning: engaging with scammers can be dangerous. I don't recommend or advocate it. Do so at your own risk.
