Hi @sumin850754 , thanks for sending the details via PM.
I have checked your account and NBN classified your address as service class 24. Meaning, the address has been connected to NBN network before and should have an existing NTD.
We have raised your concern to our Provisioning Team and a Case Manager will contact you to discuss how you can have an NBN NTD Box.
Kindly await a call within the day.
