Very threatening message that the Tax Office was filing a case against me and a warrant would be issued for my arrest. This number was given for any questions or more information. The voice sounded mechanical or computer generated rather than a real person. The "Do Not Call" register obviously didn't come across with the NBN connection. I've had lots of nuisance calls since then.

Caller: Fraudster using the "ATO" tax scam.

Didn't ring back of course! As usual threatened my arrest etc,etc!!.......... hate these blood sucking low life scumbags just trying to fleece some poor vulnerable person!
