But then I don’t get why they never ask me for money? When I get through to the scammer they just ask what I want. I’ll say “they said something about me owing money”, and they act like they don’t know what I’m talking about and get annoyed with me for wasting their time.

If the deal is “they take your money and will never get in trouble” then what’s the downside to just running the script on everyone who calls?
