Caller: Said they were from NBN

A VERY authoritative and scary female automated voice that says This is a call from the NBN network connection we have been trying to contact you as NBN is being connected in your area. Please press 1 to be connected to a technician or you will be disconnected from the internet,

The number cannot be contacted I tried calling it back but it doesn't connect

THIS IS A SCAM - DO NOT PRESS ANY BUTTONS SIMPLY HANG UP. If in doubt contact your local NBN service provider.

I know it was a SCAM as NBN will not be in my area until the end of 2020.

This SCAM has been reported in Victoria and Queensland and I am in NSW
