Prank call about tax file number and warrants

Caller: supposedly the tax office

said my taxfile number has been compromised

I called back and was immediately disconnected

Recorded message saying that my Tax account had been suspended and that I needed to call to speak to an officer or large fines would be applied. I hung up and called them back, but no answer.

A recoded message said that my tax file number would be suspended as it was being used illegally.

Calls repeatedly and hangs up straight away.
