this number tried calling my mobile, I phoned back from a landline, answered with Indian ascent and said it was the Australian taxation office.
sounded like a scam to me so I just said I called the wrong number and hung up.

Yeah, call came from (03) 9017 0191, voice sounded male with posh accent left a message to call (02) 8003 7119. The message didn't mention the ATO but said something about "tax fraud" and "time sensitive". Total BS. It's a scam. Don't acquiesce.

Caller: ATO ROBOCALL SCAMMER

Fake warrant out for my fake arrest. These clowns are calling from mobiles using spoof landlines.

Caller: “ATO” supposedly

Rang from another number- (02) 6172 0649- as I didn’t answer a prerecorded message was left stating it was the ATO and a lien is on my account for tax “avoidasion” and that paperwork was sent to me but returned unsigned and a warrant for arrest would be issued. This number was left as the number to call back. I Knew obviously immediately it was a scam but confirmed with the ATO it definitely was as they do not leave pre-recorded messages at any stage.

When I called the number back an Indian man answered the phone with “ATO” not “good afternoon, my name is ?, can I help you?”. I hung up immediately and reported this to the actual ATO. Did not give any details at any time. Have now blocked.

Call received 23.8.21 on mobile phone. Badly recorded message left on voicemail - this sounded like a dodgy scam - wanted rapid call back for "Time Sensitive" Issue .

Says they are the ATO
