Caller: NBN

I read these posts and didn't answer thinking they were spam calls. They called often! In the end I called Optus and they said it is legitimate. I answered the next time they rang, and yep they are 10000% legitimate. They were calling to get the NBN technician out here a week earlier than what Optus had booked. This is not a scam guys.

Caller: NBN...if legit

Received 5 calls in 2 days.
Returned call to a voice message...

Caller: NBN

It is a legitimate number. I was hesitant as well, but I called then NBN help number directly 1800 687 626, see here: https://www.nbnco.com.au/corporate-information/contact-us) and got through to a person who confirmed the number was legitimate. I got a call again from this number and it was an NBN technician who guided me through the remote installation.

NBN DONT CALL, only SP call you its a SCAM!
