customer complaint
customer's expression of dissatisfaction an expression of dissatisfaction with a product or service, either orally or in writing, from an internal or external customer. A customer may have a genuine cause for complaint, although some complaints may be made as a result of a misunderstanding or an unreasonable expectation of a product or service. How a customer complaint is handled will affect the overall level of customer satisfaction and may affect long-term customer loyalty. It is important for providers to have clear procedures for dealing rapidly with any customer complaints, to come to a fair conclusion, and to explain the reasons for what may be perceived by the customer as a negative response.
