NBN Installation has different Service Class types. Yours is under Service Class 33 which means TPG will send the NCD box together with the modem/router. Then, customer will connect these devices inside the house. Remote activation can also be considered.
I have since arranged for a Case Manager to be in touch with you tomorrow, 08 FEB 2021. to check the status of the installation and assist with the missing NBN NCD.
Feel free to reach out to us again should you requre further assistance.
