I didn't answer but they left an voice message with an automated voice that said they were a legal department and if I didn't call back, I would be arrested.

Missed call from this number. Voice to text message said I owed money and to call immediately. As if - total scam. Deleted the text.

Hi. Everyone Please pay attention!
To this number (02) 8091 3970!!!

I had received This call afternoon. 14/12/2018
It was voice message By A Man!

It said they are from ATO, I was quick to handup the phone.

Is scam call.
ATO never call you!
And you should know yourself, had pay your Tax every year!

I got a call from the same number. Message said it was from the legal department of ATO. I would be arrested if I didn't' call back. When called it just got terminated few times, nobody picked up the line. I assume this was a prank call. ATO has only my personal mob number whereas this came on my office mob no.

I called back number (02) 8091 3970 rang once then gets disconnected automatically.

I got the same message from this number.
