It seems that NBN is drowning right now because of the recent bushfires and heavy downpour in the last few weeks resulting in multiple outages nationwide. On top of that it seems that you will also need some sort of permission from the land lord or building management. From the looks of it wherever you go the other RSP’s are experiencing the same issues, I would recommend that you get some sort of update from your case manager and secure any drilling permission in advance.
Welcome to the Community @catdow88
For customers who would like to check the status of their service installation/activation, we have created this community article, which contains a video on How to track your TPG service installation
We also send an Email notification to our customers to inform them about the scheduled installation and if their attendance is required.
In your case, our wholesaler (NBN Co) advised us that they weren't able to complete the installation due to technician capacity issues and requires to reschedule the NBN tech visit to finish the installation of your service. Your case manager tried to call you today to no avail and sent you an Email with the earliest NBN technician schedule available.
Further updates will be given by your case manager once available.
