It's sad, but most businesses need to overhaul their customer service department. Does your company get overloaded with repeat business? Are you moving into international/global markets? Are you growing so fast you're having trouble putting new distribution protocols in place? If not, maybe your customer service needs some work.

Better customer service can make a huge impact on future business. Unfortunately, this is missed by most companies who are content focusing all their energies on getting customers off the phone. It's become almost commonplace for the customer service department to disclaim any responsibility for anything that's gone wrong with the customer's order - instead, blaming the customer first and then back-peddling if there's any proof to the contrary.
