Caller: Recorded message

When I answered this call there was a few seconds of silence followed by a recorded female voice (with an Australian accent) which purported to be from the security department of Visa and Mastercard and that my account had been debited of a sum of money. I cut the message off by hanging up before it had finished. It's the same tired old scam that has been running for a long time. I can't believe that these people actually think that anyone will fall for this nonsense.
