Out of all the advice I can give about Customer Service, the number one thing I encourage people to remember is to be grateful. Only a small percentage of customers will complain and want you to make things right, the rest just leave and you won’t know why. A customer making a complaint is giving you the chance to fix something and win back their loyalty. Even if you don’t manage to make things right it is a huge learning opportunity that points out a trouble spot where you could be losing customers and not even know it. Don’t waste this golden moment being mad at a customer, or upset with how they are reacting, be humble they took the time to help your business go further.
