This idiot called and then hung up when I answered. I have been receiving a number of scam calls in the last hour where the person hangs up as soon as I answer. This time the background noise sounded exactly like another number (02) 9410 0120 that called me 1/2 an hour earlier. I called the number back and a girl answered then hung up, but my phone wasn't disconnected, so it's clearly one of those scammers. I then called the Sydney number back and the same person answered, so it's definitely a scam caller.
