moreover:
For every customer who bothers to complain, there are 26 others who remain silent.
The average "wronged" customer will tell 8 to 16 people when your satisfied customer will tell to only 2 people.
It costs about five times as much to attract a new customer as it costs to keep an old one.
It is important to have appropriate methods to use these incidents in order to improve customer satisfaction.
