answer:Welcome to Fluther. My answer would sort of depend on the nature of the business, who commonly contacts you for service, and the type of service you provide. (Also, but secondarily, how “funky” do you want to be? The “corporate” world generally more often than not sometimes aims for clarity and comprehension in department naming, but a small boutique clothing store, for example, may be more open to funkiness. (I’d call that customer service department “Loose Threads”, for example.) “Customer Service” has always seemed to work pretty well. What’s wrong with that, except that it’s not “funky”?
