SYDNEY, Aug. 11 (Xinhua) -- Australia's telecommunication giant Telstra has vowed to invest an extra 3 billion Australian dollars (2.32 billion U.S. dollars) in upgrading its network after a series of outages displeased many of its customers with its services in recent months.
The Melbourne-based company announced on Thursday that the money for the upgrades would be invested over the next three years.
Despite the recent glitch, Telstra still managed to record a profit of 5.78 billion Australian dollars (4.46 billion U.S. dollars) for the year to June, which was a 37 percent increase year on year.
Revenue for the telco rose 2.7 percent to 26.74 billion Australian dollars (20.64 billion U.S. dollar) during the same period.
The company said that it will reward its shareholders with a 1.5 billion Australian dollars (1.16 billion U.S. dollar) share buyback after a 37 percent surge in full-year profit.
"Work still needs to be done to improve our systems and processes that can cause customer frustration and delay, and to ensure that we consistently deliver a great service experience," Telstra chief executive Andrew Penn said.
"We know that customers expect more from us as their reliance on smart devices as it continues to grow. This is why improving the customer experience is paramount, and why network interruptions in the second half were particularly disappointing."
