On: I'm a scam prevention expert and I got scammed

[mafuy]

How about this:

"Very well. Please repeat to me in writing that if I receive an unverified call claiming to be from Your bank, and asking for my personal details, that I am to give the information and follow all instructions and will not be at fault for damage that might result from this."

As they clearly won't do that, at least the moron will lose face, and quickly so.

"We don't issue written statements to customers, please call another department. We have locked your account for the time being."

The kinds of people who do this boring work all day long may not be so receptive to our witty humor.
