Have called me 3 times with (03) 8001 6042 displayed, but also call back seconds after and the screen reads No Caller ID. So they called 6 times in total, the latest being at 8:14 this morning.
I screen all my calls and reference unknown numbers on websites like this. I am also on the DNC register.

Rang me and hung up. When i called them they said number disconnected. How do they do this?

3 Rings today then stopped. Don't think it is a Melbourne Number, it started with +0380016042 If i get a call from Victoria it just comes up (03) 8888 8888 (example)
