The provided diagram enumerates various origins of complaints, as well as the average time spent resolving these issues over a period of 5 years starting from 2000 to 2004.

Overall, the criticism dominantly came from the public, and the authorities’ problem-solving efficiency was represented by a fluctuation, though the final result was an improvement. Regarding the cause of dissatisfaction, it is clear that the public accounted for 63% of the complaints, which made it the prime root of negative feedback. Both government agencies and state outsiders contributed to the data with similar figures (around 10% to 11%), which put the former at second place and the latter at third rank. In a similar vein, insurance companies’ complaining rate was only 2% less than that of the out-of-state sector. Finally, media (3%), bank employees (3%), and other sources of criticism (2%) summed up for a proportion of 8%. Meanwhile, the authorities’ response to the complaints had varied moderately in terms of the time spent per year for 5 years. In 2000, it took slightly under 6 months for the leaders to analyze and handle the situation. 1 year later, this process’s efficiency showed a reduction as the amount of time increased to precisely 6 months. However, the figure underwent a stabilization in the next 3 years, and it eventually declined to roughly 4 months in 2004.
