auto recorded voice message pretending to be the Australian Taxation Office - hung-up and have blocked

I got the same message today

left a robotic voice mail message stating I would sent to jail :/.

scam call saying if I don't call back an arrest warrant will be put out under my name and il be arrested.
number is now BLOCKED

Automated message told me if I did not return the call, an arrest warrent would be issued. No mention of what department actually called. Improper English as well!

Caller left message... "If you do not return the call an Arrest warrant will be issued & you will be arrested".... Caller didn't say what the offense was, & the message sounded "recorded". I deleted the message & didn't call back...

I rang once and got disconnected
