They called, I answered (thinking it was the number of someone I actually needed to speak to) and they hung up immediately.

Caller: ‭0485 475 896‬

Hung up after I answered, when I called back it says the number is incorrect

Caller: Scammer?

Call went silent when answered then dropped out. Called back says number is disconnected

Caller: Broadband scam

Called me 3 or 4 times over the past couple days. Picked up today and it's an automated voice telling me my broadband will be cut off in 24 hours since nbn has now been installed in my area, and that I have to get in contact with their technicians or something. Block this number

SCAM SCAM

Caller: Potential Scam?

Recorded message purporting to be from NBN, saying my phone and internet service will be disconnected and to press 1 to speak with "technician".
Call was to my mobile. I have fibre connection at home, but not landline phone. Don't have NBN to connect to... I hung up.

I called back number 0485 475 896 rang once then gets disconnected automatically.
