NBN Impersonator
A man with a heavy Indian accent, just called from a busy call center claiming to be calling on behalf of the NBN.
He advised of an upcoming 3 day outage in my area but did not know my address.
He, and then his supervisor, yelled at me, and hung up. I called the number back immediately.
I reached a man with a strong Australian accent, who was unaware that his mobile number was being hijacked.
