[constantly]

I do this. Often they hang up when they hear my voice, so I’ve found speaking slowly and like I was confused person but taking them seriously seems to be the sweet spot. From there, continuing to act confused and get their instructions wrong constantly keeps them on the line. If you mention the word “scam” or any implication they are criminals they hang up immediately and move on. They also don’t have patience for “not being able to hear/understand them.”

I think if I can take as much of their time as possible that’s less time they have to scam vulnerable people. And it’s often good for a lark and quick break from the day.
