This is such a good reminder, thank you for sharing — seriously. The “act fast” pressure is exactly what makes these scams work, it bypasses common sense completely. Your uncle is lucky he paused and asked first.
The tip about hanging up and calling the bank back directly is something more people should just have as a reflex. And the number lookup idea is underrated — having even a small piece of context before reacting can slow everything down in the best way. Saving this thread for my mom, who I’m pretty sure would panic-click anything that said “urgent account issue.” Really appreciate you laying this out so clearly.
