People who sell services often face a harder time dealing with dissatisfied customers because unlike with a product, a customer unhappy with a service cannot:

simply return or exchange it for a refund. Services are intangible and cannot be physically returned or exchanged, which can make it more challenging for a service provider to address and resolve a customer's dissatisfaction. Additionally, a customer's perception of a service is subjective and can vary greatly, making it harder to meet everyone's expectations. This is why it is important for service providers to have strong customer service skills and effective communication to address and resolve issues with dissatisfied customers.
