Call was from an identifier claiming to be NBN threatening that I was going to be hacked. When I pushed 1 to go through to the caller he identified himself as NBN. I said is this call a scam? He then went on an expletive rant calling me a f'n a'hole to which I hung up. He had an Indian type accent. Obviously there was going to be some form of attempt to get my banking, NBN or credit card details
