Craigieburn residents are among the nation’s most frustrated internet and mobile phone users, a new report shows.

The Telecommunications Industry Ombudsman’s (TIO) annual report shows that 739 complaints were made about internet and phone services by Craigieburn residents in 2016-17.

Most of the complaints were about the NBN, followed by poor mobile phone reception.

Campbelltown in New South Wales had the highest number of complaints (769), followed by Toowoomba in Queensland (768) and Hoppers Crossing (752).

The TIO received more than 158,000 complaints in 2016-17 – an increase of 41 per cent from the previous 12 months.

The report said complaints about the NBN were up 10,487 from the year before because of network growth.

Ombudsman Judi Jones said the report showed that people were “frustrated” by the internet and mobile phone networks.

“The picture the complaints show is we are frustrated when we cannot rely on technology to stay connected, to be informed, and to do business,” she said.

“Sharing high quality videos immediately, holding an online meeting or watching Netflix on the way home is the norm and part of our daily routine.”

McEwen MP Rob Mitchell said: “People are paying for a service that they simply aren’t getting.”
