A satisfied customer is the best business strategy of all.
Customer service shouldn't just be a department, it should be the entire company.

The purpose of a business is to create and keep a customer.
Customers are like teeth. Ignore them and they'll go away.
Customers may forget what you said but they'll never forget how you made them feel.
Your most unhappy customers are your greatest source of learning.
Good customer service costs less than bad customer service.
