Caller: Recorded female voice

The call showed as coming from Melbourne, Vic. The automated voice told me that it was from the security dept. of Mastercard/Visa and that my card had recently been debited $500 and that I should press button 1 to get a refund. Not Likely!! This number appears to be a legitimate home phone number, so maybe the scammers have hacked into the system and hi-jacked someone's number.
