User dissatisfaction on the high-speed internet service quality

The growth of internet usage even accelerated by the spread of high-speed internet access network such as ADSL is affecting our socioeconomic activities and culture in a great way. Korea is recently reported to be the number one high-speed internet network subscription per 100 people in the world. In a way to reflect this situation, we collect a moderate size of sample proportional to the population of each region across country and investigate what factors might explain the level of user's dissatisfaction with respect to internet service they have been receiving. The results indicate that the set of gender, age, internet usage, service kinds, incoming e-mails, and e-shopping is significantly influencing user's dissatisfaction, in that dissatisfaction is measured in 11 perspectives. In particular, user's age, gender, and e-shopping experiences are considered to be mostly explainable.
