According to the TIO’s report, for the period of July to December last year, there were 22,827 complaints related to the NBN, a 203.9% increase in complaints for the same period in 2016.
A total of 14,055 of these complaints were related to the quality of service on the NBN, and 8.757 complaints were related to the installation of the NBN
NBN CCO Brad Whitcomb has refuted the report stating that despite the larger number of complaints less than 1% of people with an NBN connection have lodged complaints. He also claims that the majority of complaints lie with the ISPs and not the underlying NBN itself, with just 5% of lodged complaints ending up on their table.
Anecdotally I don’t know a single person that hasn’t complained about their NBN connection myself, but then how many regular folk are likely to walk about town praising their internet connection?
