Listen.

Period.

Sure, you will inevitably run into people who are impossible to please. However, for the most part, the vast majority of the people who have a complaint are taking the time to attempt to communicate with you or your company about a need you failed to meet. This can be something that's broken, not implemented or done badly. In all cases, they are motivated by wanting to fix the problem for themselves...which is likely to fix it for lots of others who might not be as vocal.
