ALWAYS ask questions, it makes them have to lie more

So when you ask questions about what something means or you ask questions about why they need you to download something for them to give you a refund or if you ask them how they were able to receive alerts from your computer or if you ask the “irs” why you never got a letter in the mail before this call. It forces them to explain it. Don’t be pushy or hostile with them, just pretend to be stupid. And try to catch them in a lie if they’re inconsistent.
