Good customer service means surpassing the customer's expectations, going out of your way to address their concerns and solve their issue with efficiency and a genuine desire to help. It means being available for the customer through any hardship, and making the extra effort to get them the help they need, even if you aren't the particular person fit for solving their problem. It means being honest with the customer, being clear and transparent about policy and other things that concern then, and making sure their experience was positive enough to guarantee they return, happy and fulfilled.
