Tbh, there's really no value playing along with these scams – it's already been done (it's an old scam now) and documented many times, even by security researchers. It's not especially sophisticated, it's simple social engineering. You're just wasting your time, better to simply tell them you'll report it to the police and promptly hang up. Or do what I do, if there's an auto-dialler pause, hang up immediately, I've got no interest in whatever spam they're about to try to deliver.
