Said that he is from Telstra technical dept, that I need to switch off my computer so they can fix my internet(!?). Apparently it's been taken over by overseas hackers and now sends viruses all over the web. When I told him that I'm a network admin and I would've noticed if something like that happened - he immediately disconnected. Scammers.

I am getting harrassed by multiple calls with no one on the line. Not funny!

4 calls in 2 hours today! Intermingled with another bodgy caller . Both hung up. Sick of them all
