I got a call on this number with an automated recording telling me it was the NBN and my phone and internet would be disconnected in 24 hours. It then told me to press 1 to stay connected, which I did. I then told them I don't appreciate being called and threatened and they hung up, I tried calling them back but it said my call couldn't be connected. I then went to the NBN website and clicked on 'protect yourself from scams' and sure enough, they said if you get such a call hang up.
