I called back number (02) 6188 5690 rang once then goes to busy tone.

automated message said was from aus taxation but did not know my name....spam...trying to get monies

received this voicemail:

"I need you to your retained attorney to return my call. The issue that handed extremely time sensitive. My name is officer Matthew..."

It was an automated message from someone that had poor english that sounded like a computer generated voice a bit also. Super weird.. Hung up after a few seconds though because it was clearly not a real call.
