Semi topic related, there is a streamer named KitBoga that just messes with scammers, he's basically a voice actor and does different voices and acts like hes different people, the videos are pretty hilarious.
Yeah he is very fun to watch. But just like everything else you see on TV/the internet, it's best to not try it at home. Too easy to give the scammer information they shouldn't have even when jerking their chain. And you've just told them you're a real person with a real phone number who answers the call - maybe the next one will fool you. Not worth it; just hang up.
