Customer service skills involve understanding customers' needs and wants, providing reliable and quality service, and prioritizing customer satisfaction. Good customer service differentiates successful companies from unsuccessful ones. While most customers do not complain, those that do often do so due to bad service, improper handling of complaints, or the business not making customer needs a priority. Superior customer service involves being reliable, assuring, customer-friendly, empathetic, and providing a quick response. Key behaviors include being polite, attentive, respectful, considerate, and helpful. When dealing with customers, representatives should greet them with a smile, listen actively, apologize for any mistakes, and ensure all customer needs and complaints are addressed.
