Poor customer service occurs when a business fails to meet the needs and expectations of its customers. This can include long wait times, unhelpful staff, or inadequate responses to complaints. When customers feel ignored or undervalued, it can lead to frustration and dissatisfaction with the brand. Additionally, poor customer service can damage a company's reputation and result in lost sales. Customers may choose to share their negative experiences with others, impacting potential new customers. Businesses that prioritize customer satisfaction and invest in training their employees can avoid these pitfalls and foster loyalty.
