Telco complaints have risen from 8.7 to 9.3 complaints per 10,000 services in operation (SIO) on average, according to the latest quarterly report published by the Australian Telecommunications Industry Ombudsman (TIO) and Communications Alliance, with the increase attributed to the industry changes brought on by the National Broadband Network (NBN).

During the quarter to March 2018, Telstra's complaints ratio was 9.5 per 10,000 SIO, up from 9.2 last quarter[1]. Vodafone's ratio rose slightly from 4.9 to 5.0 complaints per 10,000 SIO, while Pivotel's went from 0 to 1.

Optus' complaints ratio jumped from 10.6 to 12.1 complaints per 10,000 SIO.

"This result highlights that our industry is still struggling with the disruptions caused by the rollout of the NBN and the transformation of communications delivery platforms," Communications Alliance CEO John Stanton said.

"Though the numbers are very disappointing, we are continuing our work on customer-centric initiatives with government, regulators, and consumer representatives to improve the overall customer experience."

Amaysim was the only provider that saw a decrease in complaints during the quarter, with its ratio dropping marginally from 1.4 to 1.3 complaints per 10,000 SIO.

Every quarter, the TIO in conjunction with Comms Alliance publishes a Complaints in Context report covering landline, mobile, and internet service complaints from residential and small business consumers.

The report comes on the heels of the TIO's 2017-18 half-yearly report published earlier this week, which showed that NBN consumer complaints to the TIO more than tripled[2] year on year to 22,827 for the first half of the year.

According to the TIO, most NBN complaints were about provider response, at 10,222 in total; poor service quality, at 9,006; connection/changing provider, at 8,929;
