Dear Zappos,
I want to tell you how completely satisfied I am with the way you have handled my order of tennis shoes. Both by telephone and over the internet, you have been totally professional, helpful, understanding, and generous. Not only have you promptly filled my orders, but you went out of your way to find replacements for the original shoes you sent me which did not have the soles that I wanted and had expected from the pictures in your internet catalog. Thank you very much -- I will be back to shop with you again because of your exceptional customer service.
William F.
