Welcome to the Community!
We apologise for the long wait time on the phone as our tech team is getting high volume of calls due to internet issues caused by the severe weather condition in the past days.
Based on the recent update on your account, the issue is now raised to our Engineering team after performing troubleshooting with our Technical support. Kindly allow them sometime to assess the issue but there is a possibility that a tech visit is necessary.
We have raised this to NBN Co and is awaiting updates.
