Outstanding customer service: friendly staff, great communication (you get a live person quickly), orders always correct. Now, I have never had to return anything so, I do not know anything about that- however, I am a tough customer and I have high standards on how I should be treated as a customer and they have checked all those boxes. It is funny with all the business I deal with there are only two I give 5 stars to and both are animal related! My two dogs, George and Molly love their dog food and the delivery man. I know the delivery man is not part of Chewy but delivers the dog food right to the barn and gives George and Molly treats. They know when it is the Chewy delivery!
