After Vodafone Hutchinson Australia logged a 222 per cent jump in complaints before the Telecommunications Industry Ombudsman for the year with 55,600 complaints, the company announced Thursday that it will put in place measures to improve service.

On top of the innovations are 1,500 new sites in its new 850Mhz network by middle of 2012 and a customer contact system that monitors Vodafone's contact centre, Twitter and Facebook accounts and e-forum.

The Ombudsman pinpointed to the rising number of complaints over Vodafone's network problems as one of the two major causes behind the increase by almost 25,000 complaints received by it for the year. The other factor was the increased market share of smartphones.

The 1,500 new sites would be on top of Vodafone's current 900 sites in its new 850Mhz network built for smartphone and data and 2,000 sites in its old network which had been replaced with new equipment.

Vodafone also added 300 customer service advisors in Tasmania and Mumbai to reduce caller wait times.
