Explanation

A complaint is an objection to something that is unfair, unacceptable, or otherwise not up to normal standards. If your neighbors have a complaint about noise, they want you to be more quiet. A complaint is voiced objection to something, like a complaint about cold or disgusting-tasting food in a restaurant.
