I was able to get through to TPG customer service and a manager helped me connect to internet using TPG issued modem. Just waiting for phone line to port after installation is finalised on TPG's end.
Welcome to TPG Community!
We have located the account using your community details and we can see that your NBN FTTC service is now working.
The Home Phone Number porting normally takes 1-5 working days from the time the service was activated.
Feel free to message us should you need any assistance. Thank you.
