We don't complain enough in this country, which is one of the reasons why service can be so bad. However, those who complain constructively have worked out they can even make money through it. A well-crafted, reasonable letter including a request for financial compensation can make you money. Write to a company's CEO explaining the problem and set out the amount you feel you should receive in compensation. If it is refused write again, and even write a third time if necessary. Usually by the second or third letter they cave in and give you about half of what you were asking for.
