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.

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.

received a call from this number on my mobile phone, but I didn't answer it as didn't have my phone with me.
