Answer:
A company's customer service department interacts with customers after they have purchased the product.
Step-by-step explanation:
Customer service is the provision of customer service before, during and after the purchase of a product or service. It consists of a sequence of actions aimed at increasing the level of customer satisfaction - that is, the formation of the client's feeling that the product or service meets his expectations.
It is useful for a company to analyze customer service requests to learn how the product can be improved, but also how to generate additional revenue from accessories, etc.
