Got a voicemail message from this number, with a robotic voice claiming I had to call them back or else they would issue an arrest warrant (they did not specify a crime). Obviously some sort of scam, as no reputable organisation would do things remotely like this.

Got the same voice message and when I phoned back, rudest lady answered. I said to her it is very noisy in the background, she said it is a call center you know.... and then She asked me for my details... I started but something felt wrong I said I'm not comfortable giving you my details, and she screamed at me well you better get a lawyer cos you going to jail for fraud!! When I asked for what she said she won't give me details but I better get a lawyer and put the phone down!
I have reported the number to the real ATO.

Indian ratts from overseas trying to steal money

Used robocaller to leave a voicemail. Threatened me with a lawsuit and arrest warrants.
