This number has been hijacked by Indian computer scammers, "hello my name is robert and your computer modem has been causing computer viruses blah blah blah". Hang up, don't give them any information, report it to the ACCC Scamwatch website. Phone you local politician at home when he or she has settled after a meal or during the day, heck, any time of the day or night! Tell them to get this mess fixed NOW!
