Automated saying it was the tax office.

Caller: robotic voicemail

Indicates 'tax avoidance' and threatens 'arrest'. Smells fraud/criminality because ATO sends email/paper mail and NOT absurd voicemails.

Left a voicemail saying something about registered documents unsigned, a petition and I’m going to jail lol oh and to call back

Caller: spencer? Spence?

some muppet trying to impersonate the ATO. The tube left a crappy recorded message saying a warrant was out for my arrest for tax evasion activities.
reported it to the ATO.

Automated message claiming I had perpetrated tax fraud and there was a warrant for my arrest and told me to call the number back. Won't be doing that.

Left me an automated voicemail saying there was a warrant out for my arrest. Seemed like a spam call. Obviously did not call back.

More Tax Scam now from this number.
Be careful.
