Purportedly from NBN threatening to cut of the landline within 24 hours if we didn't connect to the NBN because it was nowavailable in our area. Funny that when we got a letter from NBN two weeks ago saying that there going to be delays in connections because of "technical issues".
Voice was a synthesised recording and invited us to "press 1 to connect to the technicians" who could solve the issue. CLICK.
Called the number back, surprise, not connected!!!
