When customers are dissatisfied with the service you are providing they will be one of three kinds of complainers: aggressive, passive or constructive.
Aggressive complainers are most difficult to please and are often more concerned with displaying their emotion than actually achieving a solution.
Passive complainers are the most lethal to a businesses success, as they will complain to everyone but the actual business. Since the business is left unaware of their error they cannot correct it and the only thing a passive complainer succeeds in doing is depriving the company of potential business.
Constructive complainers are most beneficial to a business since they address their problem to the business in a calm, rational manner.
Whatever type of complainer they may be, it is important to deal with all complaints with the utmost care. After all, the customer is essential to business success.
