“When customers arrive at a Web site, they have goals and tasks they want to complete—for example, buying a movie ticket, transferring money, signing up for a service, applying for a loan, asking for help, and so on. An important requirement for a Web site is the ability for customers to serve themselves, so they can generally complete their tasks without needing to contact Customer Support or ask a friend for help. However, understandably, there are times when customers do need help from Customer Support—by either speaking over the phone or using live chat—so they can solve more complex problems or complete tasks they cannot complete on their own. In such cases, customers need email addresses and phone numbers that let them contact Customer Support directly.” (Daniel Szuc – UXmatters)
