your customer, maybe there is someone else in your company that is; watch what you say, how you say it and know to whom you are saying it.
when you are wrong, say you're sorry, even if you do not think it is important to say it. those words, "i'm sorry," if said in a genuine and caring way will prove to your customer that you really care about their business. follow through with action and correct your error as best you can, as quickly as possible. don't forget to follow up with the customer to confirm you fixed the problem and corrected yourself and that your customer is satisfied.
