Optus has overtaken Vodafone as the most complained-about phone and internet provider per customer in Australia, according to an industry survey.
The Telecommunications Industry Ombudsman on Friday released its contextual complaint figures, which show the number of complaints per 10,000 services provided. This acts as a way to gauge the service levels of big and small players on a relatively even playing field.
The average number of complaints per 10,000 services across the industry are at their lowest level in 18 months, falling from 7.6 in April-June 2014 to 6.5 in the latest figures from April-June 2015.
Vodafone Hutchison Australia has garnered the most new complaints per 10,000 customers for the past five quarters, leading it to vow to become Australia's favourite telco by the end of 2015.
