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 once the service is activated. If you have received this email and the service is still not working, we recommend to check if the equipment is properly set up by going to this link : New Connection Setup Help
In your case, our NBN Provisioning team received a failing result after testing the line and booked an NBN technician to finalise the installation/activation of your NBN service.
Further updates will be given by your case manager once available.
