This pie chart illustrates how people rate the customer service between the 5 year period. Ratings were classified into 5 different classes: excellent, satisfactory, good, poor, and very poor.
In a glance, there was a considerable growth in the rates of both good and excellent customer service responses. In the meantime, other responses show a drastic drop in the second year of the survey.
In 2005, satisfactory-rated responses were the highest by 45%, followed by good-rated responses which was 14%. Contrastingly, poor-rated responses were the second highest in 2005 (21%), and very poorly rated answers were 15%. In the meantime, the least rated responses were the excellent ones (5%).
In the second year of the survey, the peak ratio was good-rated responses which were 39% of overall results, followed by excellent-rated (28%). In addition, owing to changes, satisfactory, poor, and very poor rates fell drastically to 17%, 12%, and 4% respectively.
