Started to get missed calls on my mobile from this number. When I try to call back I get an automated message saying the number is not connected.

So bloody annoying!!! They've been calling me every day now without fail over the last week & as soon as you answer they hang up! Wtf? Don't know if it's another one of those "would you like insurance" nuisance calls or what?

Unsolicited "hang up" calls...possibly Telstra?
