i just had a call from this number.  As I didn't recognise it, I didn't answer it.  It rang for the whole 20 second ringing duration.
I called it back, but it just beeps and doesn't go through to anything.

received a call from  above number, don't know who they are.  I didn't answer my phone as I didn't have it with me at the time.

Spam spam spam. I had a missed call from this number, but my phone only rang for about a second (deliberately short I reckon). I called it back and there was a recorded message saying "Thank-you for calling. We may have recently tried to invite you to take advantage of a personalised offer made by one of Australia's major brands, or in regards to an existing relationship you have with this brand. PCI will try to re-present this bargain before the offer period expires."

If they do call me back (I hope they do, I love doing this sort of thing ;-), I will be wasting heaps of their time, and asking where the HECK they got my phone number from given it's not listed.
