Western Union Mastercard scam.

left a message on my voicemail "this is a call from visa and Mastercard security to confirm a transfer of $601,100 to Western Union.
Please press 1 to confirm or 2 to speak with customer service". I rang back 3 hrs later and got a recorded message "the number cannot be connected"

Western Union Scam call

The number says 03 which is Victoria/Tasmania yet the phone says it is Wentworth New South Wales. No-one on the line. I now do not speak and it prevents the voice recognition software they use from connecting the call to the scam artist behind the call.
