Welcome to the Community!
Thanks for raising this with us. I'm sorry to hear that you had difficulty contacting our Helpdesk for assistance regarding your concern.
I checked your account using your community details as reference. I was able to perform diagnostic tests and we found out a possible NBN line fault that needs to be checked by NBNCo. I have escalated this case to our Engineering Team to assist us in getting your service back up and running.
Please expect to be contacted (SMS or phone call) by our Engineering Team before 4:30PM NSW today to provide you a feedback on the ticket's progress.
Our records indicate that one of our Engineers have already spoken to you about the case. This was already raised to NBNCo to resolve the issue.
Any additional information about the ticket will be provided to you directly by our Engineering team.
