2 rings and then hangs up. Typical scammer. Wants you to call back to verify your number and you pay for call. Then the hard sell starts.

Caller: (02) 9000 7010

Doesn’t answer , hangs up

Persistent caller. Never leaves msg.
I never answer. Have blocked number

I found this number as a missed call on my mobile; no idea who it could be. Also, the call came through at about 6.00 a.m. or a little earlier, so very unlikely to be legitimate; most likely to be a scammer.
