Our sincerest apologies for the inconvenience.
We've checked this with NBN Co and we were advised that they've identified that a Tap Upgrade is required before the connection or installation can progress. We did not receive an estimated time to complete the job, but we were advised that they'll give us update within the next 2 Business days.
They need to make sure that there's no further fault within the NBN HFC line in order to release a new appointment to complete the order.
We'll advise our NBN Service delivery team with this case and have a case manager to contact you for further discussion.
Let us know if you need further assistance.
