The old saying “kill them with kindness” could not be truer in a situation with a customer complaining. But rather than smile and pretend to care, genuinely let them know you are thankful they are sharing with you their complaint. Tell them that you appreciate that they are taking the time to talk to you about their concern and you want to make sure you understand exactly what they are saying. Then … actually listen to what they have to say. This opens up the opportunity for dialogue and problem solving.
