I never give any information to anyone who calls me, apart from people I already know like friends and family. If they say they are from the bank I apologize and say that I will contact them independently via the number that is on my card. I don't even confirm my name. Some banks think I am being difficult, but I stick to this principle regardless.

I think it's more likely that some scammers think you're being difficult. Shouldn't that be standard procedure for a bank?
