Hung up :(

0420 770 160 keeps calling, multiple times a day, but leaves no message... can only assume it's some marketing scam...if no message is left, I will never consider answering the call

Called me 4 times in one day. So annoying.

Rings 4 times a day every day. I never answer

Caller: Unknown

Called me 6 times in the past 3 days
The number is “disconnected” if you try and call back

Dodgy

Hung up? Grr

Not connected

They hung up - called me twice and hung up after few seconds. When I called back there was automated response from Optus saying the number had been disconnected.

I called back number 0420 770 160 rang once then gets disconnected automatically.
