In any customer-related department, especially in customer success and support teams, it is important to know how to deal with any type of customer. People might have different backgrounds and manners while approaching a subject or when there is a problem with their experience.
Like in any other business, e-commerce customers may encounter problems or need answers to their questions throughout their shopping experience. Customer service in e-commerce is mainly for helping out the existing or prospective customers or providing them with the information to find a solution themselves.
