They hung up when I answered.

I used the google screen call function/voice mail on my mobile phone and they hung up without proceeding to leave a message.

Claiming to be from NBN and said my service had been compromised. I said no it wasn't and hung up. They called again the next day from the same number.

don't seem to be a genuine AGL guy, they kept on asking and selling the plans with new rates and charges but when i asked to call them back on AGL number, they insisted to call me back instead.

who ever called dont have decent respect in manners. leave message who you are then i will return the call. no message you can jump in the sh*t creek. i am over it with all those unknown marketing / desperate callers. !!!!!

I did not answer as I did not know the number - surprise, surprise they did not leave a message.
