I called back number (03) 8592 9366 rang once then gets disconnected automatically.

called a few times. doesnt leave a message. robocall. will be blocked

Called back and stated "you are being called by a marketing company, if you wish not to be called again, please press 1".

I hung up. Has called a number of times, without leaving message.

Same here, just another moron who needs a life.

Doesn’t leave a message / calls repeatedly & hangs up. Probably a scam.

Caller: I don’t know.

Caller said hello and hang up. Such nuisance.

Caller: Spam

Caller: Selling solar panels

Caller selling solar panels. Very patchy connection

A con and scammer.

Calls then hangs up.

Caller: Calling from "Melbourne"

Says they are calling from "Melbourne, alright?" "Calling from the Government" something about a solar panel initiative and trying to get me to agree that I own a house. Asking to speak to their supervisor got me hung up on.

Many multiple calls almost every day. Call back and its goodbye. Time waisting idiots

I got a missed call on my mobile phone. No voicemail left. I called back the number and it had a message that just said, 'Goodbye' and disconnected my call.
Yes, 'Goodbye' is the correct response - number is now blocked.
