Welcome to the community!
I was able to locate your account using your community details and seen that your NBN service installation is still in progress. Installation of NBN service can take between 2 to 30 working days depending on the demand of NBN services in your area and the availability of the nbn™ technician to perform the installation.
You can also visit www.tpg.com.au/install and enter your username to check your latest installation status.
Let me know should you require further assistance.
