You NBN-HFC install has been put into ''HELD'' by NBN. There are issues with the cable from the street to your house. NBN are responsible for the street infrastructure and this is out of TPG and all retailers control.
NBN will repair this in due course but have not told us anything as yet.
I will arrange an install officer to call you back for an update and to discuss your options, but again, we have not heard back from NBN yet and may take a few days for them to update us.
