I had excactly the same problem with you.(they booked a technician to come at my place)
They can't activate your connection remotly so they have to sned a technician at your place.
You have to get in contact with one of the case managers and tell them that you followed all the instractions, you left the nbn box 24hours on and they will arrange a technician.
