Totally agree - this number is from NBN

Caller: NBN

Mine was a legitimate call regarding the installation of an NBN Service.

Caller: NBN

Legitimate

Caller: NBNco Infrastructure

NBNco left message on my answering machine to say the problem I reported with their infrastructure on a power pole was going to be investigated today.

We've had a lot of problems with people nicking the old copper wires and damaging actual power wires as well, and making the stobie poles (concrete with steel frames) live... So I reported with the snap send solve app. "pit and equipment - nbn". There were loose wires hanging from the bottom of the power pole.

Finally got a way to report to them (snap send solve app), maybe they will clean up some of the redundant infrastructure.

Caller: NBN

You would think the NBN would at least make their own phones work properly, HA! They called at least 5 times this morning but everytime I answered the line was dead as though they had pressed mute at their end. Still haven't been able to hear them and the last time they called I suggested they try some other method of contact.

Caller: NBN

Not scam. It was call from NBN who my iSP said would call because I contacted the ISP and said I was experiencing NBN connection problems the previous day.

Caller: NBNCo

Legitament call from NBN Co about a complain I had lodged a few days ago

Caller: NBN

I lodged a ticket to have NBN pit lids replaced as they had become damaged and were a hazard. The caller was the Case Manager for nbn Damages and Urgent HSE updating me on the status of the job.

Caller: NBN Co

This is a legit call to confirm a pre-booked visit by an by NBN Co Tech to visit our office. They left a message with the exact details of the appointment.

Spoofed number that, if you call, recorded message claims it's nbn and states 'please note that his number does not have a call back feature'. If you listen to the message on nbn's contact number, they advise about scams and state that they rarely call clients directly. Very aggressive call pattern. I declined 6 calls in the space of 2.5 hours. Nbn must have a data leak because I did have an appointment booked for the next week. However, as usual, I received a confirmation text the night before, asking me to confirm with a YES or NO via text. Nbn do not call to confirm technician appointments.

NBN call about technician appointment. They only discussed reschedule of appointment, date/time and confirmed address for appointment that's all. No other details requested. When the call ended, I received a notification within 2mins from Telstra confirming the appointment we agreed on during the call.
NBN website says "nbn will never call and ask to access your computer or advise you that you’re going to be disconnected." (https://www.nbnco.com.au/learn/protect-yourself-from-scams)
Calls that start talking about your system being hacked or about security breach and need access to your system or payments to secure the appointment or to avoid disconnection or unsolicited install of additional services, is very likely a scam. If in doubt, hang up and call your provider directly.

Not a scam, just NBN checking details for tech comes out

I think its legit coz they know my address and booking time for my NBN appointment.

Caller: Nbn

Caller: NBN Co

Legitimate call regarding an NBN technician appointment

Caller: NBN

This is a legitimate call from NBN Co.

Caller: NBN

LEGIT CALL FROM NBN
Rang to discuss an issue with NBN

Caller: NBN

I reported an NBN line down and they called me to let me know a technician was coming to fix it

Caller: NBN

I am inclined to agree with Ange here: when you call it back it is an unattended number but when I checked my call history with that number on my phone, I have one or two calls of a few minutes each on that number and it times with when I raised a damage repair issue with them. I advise that if you have contacted NBN in the recent past, check if you have a call history with this number. If you do, there is every chance it is their customer service response centre.
