Getting regular, couple times a day to both my Mobile and Landline phones, from numbers like this that identify as being from "someone" named Sydney, Brisbane, etc on screen of Mobile. I don't answer ANY as I know its not anyone I know and since they have never left a message that supports my opinion. Just repeated nuisance, not asking for info or call back or such (since no messages ever left) but I simply don't answer calls I have no idea of. Thinking possibly to do with NBN providers trying to drum up business with it approaching time my landline is switched off - actually is 5-6 months until scheduled to happen but I know they try and get in early to have you on their books for when it is time and there is no option but to switch over, something I am leaving until last minute to give NBNco the chance to dump their pathetic plan of predominantly FTTN based NBN everywhere and properly rollout at least FTTC but preferably the original plan of FTTP / FTTH before I have no choice.
