I'm sorry to hear that your NBN installation has been less than favorable. I can see that a Provisioning Case Manager attempted to reach out to you today, but they're unable to get hold of you to discuss the case.
I took the liberty to go over your case. I understand that the order had to be resubmitted, hence the reason why an installation appointment was booked to progress the new order. At this point, NBNCo has tagged your order as In-Held because remediation works are required to run a 10-12 m underground Lead-in conduit from the pit. In addition, trenching needs to be done. It was noted that permission is required from the neighbor and Strata to run the Lead-in Conduit. We suggest that you remind the parties involved about the remediation works. The planned remediation date is scheduled on or before October 29 which is subject to change. Further updates will be coordinated with you by your assigned Case Manager.
