Two things you should never say to a customer: 1) "That's our policy," and, 2) "There's nothing I can do." The "That's our policy" excuse allows employees to take cover and avoid having to take action to help the customer resolve their situation. This phrase is the last thing your customer wants to hear when they're already upset with you. It's kind of like throwing salt into the wound. The "There's nothing I can do" excuse is nothing more than a cop out used by lazy employees who do nothing more than sleep walk through their job all day. Regardless of your company's policies and the limits of empowerment you give your employees, when it comes to customer service, you make every effort to make things right for your customers or else your competitors will.
