I rang once and got disconnected

I got a call from this number, and as it came up 'unknown', I didn't pick up. They left a message saying they were the ATO and that if I didn't call back they would arrest me and the police would pick me up. My daughter investigated and it came up as a scam.

Artificial robot voice told me there's a lawsuit about to commence and if I don't call their requested number I'll be arrested... lmao

Recorded message claiming to be from Australia Tax Office.

Caller: Robo voice claiming to be from the ATO

This is the scam the Police are warning people about at the moment. The robo voice with an American accent claims to be calling from the ATO and says there is a lawsuit filed against you. Apparently you need to call back asap to stop an arrest warrant being issued. If you call back, they demand payment in Bitcoins or iTunes cards. There is so much wrong with this ...

Claimed to be the ATO calling me to investiagate a lawsuit - I believe it was a scam but I don't know
