I got the same call at about 11:35am.My concern is what would have happened if I'd pressed a number instead of sitting there silently.  The call was disconnected when I didn't hit 1 or 2 within a few seconds.My number has been on the DNC register for a very long time.It makes me wonder what our government is doing about this type of activity.  It must be legal.Ridiculous!

was called on mobile, but I didn't answer

Got this call 16.07 - didn't answer.  Rang back on land line - got hello and the was disconnected

Call this morning.  I didn't recognise the number so it went to voice mail.  Checked my voice mail and it was a recorded message for a quiz.  Deleted VM.  How do I ensure I don't continue to receive calls from this number?

I got called at 12:20, missed it, so I called back and it answers exactly after one ring, then hangs up so I just assumed it was an automated/ computerised message

In general, if it is a pre-recorded quiz then hang up straight away because you might be being charged like $5.00 a minute. They want you to continue the connection to rack up the charges. Simple scam.
