I received the same message but from different number (03) 9016 3971

Don’t ring back scammers

ATO Scammers and I wasn’t realises also they took accountants number and call from accountant number lost 10k using bitcoin

I received the same message. A robot voice stating that if I didn't call their number back within a week, a warrant for my arrest would be issued. No other info given, just to call their number. Ridiculous. Another reverse search of this number came up with a company in Melbourne called "Symbio Networks".

I just got the same from the same number

missed call from this number, voice message left by said number which was a really weird (American voice) message saying 'if you don't respond an arrest warrant will be placed???'
