Scam from Telstra saying “ has done suspicious with some illegal and criminal activity”
This is very time sensitive and I need to call back urgently.
Probably not from Australia due to the language used but definitely a scam.

Caller: Apparently working on behalf of ATO

This person called me and an automated voice came on saying that my ATO was under threat of suspension due to suspicious activity and I had to press 1, then he said I had to press 1 again. It didn't sound right to me so I hung up and called the number back, it rang but no-one answered the phone. I hung up and called again and it came back as caller busy. Don't trust this turd if they call you.

Sounded doggy - seeking suspend tax file number - WTF?

VOICE RECORDING STATING MY TFN WAS SUSPICIOUS AND THAT I NEEDED TO PRESS "1" TO SORT THIS OUT. I HUNG UP. I CALLED THE NUMBER BACK BUT IT RANG OUT.

Message left.... This is time consuming, please contact this number as soon as possible before your assets and pension is confiscated....
There was no name or Organisation name.
Re called no. No response.
This is very worrying.
