I think it might be time to let the general public know if you give out your details over the phone on an incoming call then you're the only ones to blame. These idiots you hear of where their "bank" has called them to alert them to some fraud and due to a police investigation they need to send a courier/taxi to collect their bank card and oh by the way we need your pin number too.....II best the fraudsters couldn't believe it when they discovered that scam worked.
Biting the hand that feeds IT
