oh great :/
What irks me is that people would likely fall prey to such calls because they have been conditioned by their banks to not expect any form of security over the phone. Anyone tried verifying the identity of a bank representative calling you? The logical paradigm that ensues is hilarious.
"Hi this is Barclays calling about a query you made, for security i need you to verify a few details with you"
"This is for security, what is your mothers maiden name?"
"no, i need you to first prove you are from my bank, what is the last 4 digits of my account number?"
"I'm sorry i cannot do that sir, data protection laws forbid me to give out account details until you are verified, could you answer the question?"
"no. unless you prove to me you're from barclays, i'm not giving you anything"
"Of course i'm from barclays, I have your phone number"
