Called, and when I said nothing and waited for them to introduce themselves, they hung up. Nuisance caller, scammer, or crook of some kind. Maybe that horrible unethical YELLOW BRICKS mob that has an automated calling system set up to waste people's time so as to save them a little. Real cheeky creeps.

Missed call. Called back but couldn’t get through. Blocked

Was told that they are market research company. Told guy (Aussie) that I am on Do Not Call Register.
Don’t care what he wanted - hung up.

called and no message left. I suspected this call from an unknown number was a hoax. Good to see I'm not the only one

Caller: (02) 8550 1506

phone rang no contact hung up before other language phone answer

Spam

Apparently they are helping find a better health fund but seemed very dodgy, sounded like they were muted after what they would say.

is there tech to block these calls
