Maybe it's because I'm from a country that is full of 2FA scams exactly like this (particularly for WhatsApp), so I could immediately tell it was a scam, but I didn't find this convincing at all.

They call you, and then they ask you for stuff like the last four of your SSN and what loans you might have with them to prove that they're speaking to the right person. They act surprised when you don't want to answer because they called you.
