Robo call announcing from Centrelink (on a fixed-phone number which is not given out AT ALL as we use mobiles) saying that pension has changed. "If you are in receipt of a pension press 1". I would suggest that if it was calling only pensioners it would know whether you were on a pension or not. Just hung up so not sure how the call would have proceeded.

I had a missed call on my mobile from this number today, Friday 14th Sept at 5.40pm as per my phone record. Centrelink closes at 4.30pm. I did call back to find out the identity of the caller. I was greated by a recorded message, female voice, sounding robotic and with American accent, saying: "you are a caller number 5 and that the approximate waiting time is such and such.There was no mention of who rang. I hung up.
I had another missed call at 6.30pm. ??
