Hello Everyone,

I have a number 021 700 311 which has been for many months showing up in my billing logs in Kogan Mobile but I have not been calling (virtual provider on Vodafone's network - apologies if I have the wrong forum for this post.) 

This number is not one I have been calling, nor does it show up on my iPhone's recent calls list.

When I do call it, it has a short recorded message and then ends the call after around 4 seconds; but some of the calls to this number in my carriers billing system show a duration of up to 206 seconds.

I found 1 service online which showed this as a 'redirection' or 'call forwarding' number, but a normal google search pretty much brings up nothing apart from "Nuclear Waste Program: Hearings Before the Committee on Energy and Natural..." and some dodgy dating website links and ends after 3 pages depending on the search pattern (021700311 or 6421700311 or "021 700 311" etc). 

Also a bit strange for such a short google history for a number which I assume according to it's length has been around since BellSouth? Or has the new number portability rules changed all this? :-

I called a friend who works at the carrier and he put it down as a billing error; and said I should contact the actual service provider Kogan (an excellent response :-) and one I followed, a few months ago and put a much smaller summary of this into their chat window and my browser closed itself down on me. (dark evil music plays.) 

I then became distracted by a myriad of other things, and am now circling back around to track this down, as I believe it's related to a recent hacking attempt. 

76 calls in approx a month; 

I've asked some of the finest minds in the NZ security/hacking community and other more, ahem official sources but no one has been able to cast a light onto what this is. Can you?
