We truly understand the frustration of not being able to use the service as expected, @Michaelherps.
As you are aware we rely on NBN Co in your area to provide a service and appointment availability is subjected to our wholesaler partner and as a re-seller we only have limited control over such things. Please understand that this technical limitation is beyond TPG’s control.
Our Engineering team is doing the best they can to ensure that everything follows through and that necessary updates are provided whenever it's available.
We sincerely apologise for what happened, @Michaelherps. We have forwarded your message to our Engineering Team and we'll make sure that someone will contact you today to discuss the status of the case.
