Caller: Australia who then became a foreigner speaking on an 02 nubber located in Exhibition Street Melbourne1 HELLO??????

Obviously fake advising Internet/Nbn where my phone will be disconnected and I should "Dial 1" to get help from Telstra. I followed through for "fun": and guess what they needed access to my internet until I told them I was involved in IT then they quickly hung up! BEWARE - remote access means they can do what they like with your equipment and maybe any data stored in it!!
