Thanks for raising this. I'm sorry to hear that you're left without any internet connection after the NBN service got installed.
I checked your account to have a better understanding of what happened. From what I can tell, the installation was already tagged as complete by NBNCo. However, as communicated to you earlier when you spoke to our Helpdesk Team, there's a fault that NBNCo needs to look into. Our Engineering Team has already raised this to NBNCo for investigation, but we're still waiting for a response.
You will be contacted by our Engineering Team via SMS or phone call once an update is available.
If you have other concerns that we need to look into, please let us know.
