Caller: They say they are Telstra Nbn security or something.

I rang this number back and it is a business on the Mornington Peninsula Vic. They have had others ring back and are now looking into it. So someone is piggybacking their number saying they are something to do with Telstra Nbn security.

Calling no stop not answering,going to message bank and they hang up, answered once an Asian woman said they were going to keep calling, and what was I going to do about it, unplugged phone now.
