Customer service is the support and assistance provided to customers before, during, and after they purchase a product or service. It aims to ensure that customers have a positive experience and feel valued. Good customer service can include answering questions, resolving issues, and providing helpful information about products or services. Effective customer service can build strong relationships between businesses and their customers. When customers feel heard and appreciated, they are more likely to return and recommend the business to others. This can lead to increased loyalty and sales, benefiting both the company and its customers.
