SCAM!!!
I answered this number and received an automated message that my NBN would be disconnected and to fix it, press#1 to be connected to a Telstra operator. So I played along..Spoke to an Indian fellow who's name was Brendan (seem legit!). He wanted me to log onto my computer and take remote access to fix the problem. I pretended to follow his instructions and gave him a fake IP address the address I gave him was g.o.f.u.c.k.u.r.s.e.l.f. He hung up straight away!
