Welcome to TPG Community,
Could you PM (Private message) me your customer ID, username, service address or mobile number so I can check the status here.

The reason you were not shipped the NBN Connection box was because there has been a previous FTTC installation at your unit.
Prior tenants are not supposed to take this connection box with them when they move out.
I have escalated this to TPG NBN Installations and they will get in contact shortly.
