Caller: “Australian taxation office”

Apparently it’s the ATO and they did an investigation into your file and you need to get a lawyer because they are taking you to court

This is a scam.
Please report these phone calls to the real ato as they do give this information to the police.

...there is a lawsuit case being filed under your name. The moment you receive this message I want you to get back to me on this number. If we don't hear from you we need to issue an arrest warrant under your name and get you arrested, so get back to me as soon as possible

Caller: the "ATO"

Apparently, these people are insane. I called them back and was told to "call your mom", and when I tried again, I was told that the man answering was my"daddy". I've heard of stupid 'phone calls before, but this one takes the cake!

Caller: Audit department of ATO

There is a lawsuit against me. Need to call them back to discuss further

I called back number (02) 8091 2058 rang once then gets disconnected automatically.
