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 : NBN Hybrid Fibre Coaxial (NBN HFC) Setup Guide
In your case, the NBN technician visit has been rescheduled and the information has been sent via Email. Our NBN Provisioning team is monitoring the account and a case manager will be in touch with you via SMS/Email or phone call once an update becomes available.
