If we were to dissect the types of business letters further, there are mainly six types.
Acknowledgment letters are a professional courtesy, meant to acknowledge the receipt of something, or to acknowledge a fact or an error. It usually entails a short detail of the day something arrived and a note of thanks.
Complaint letters are meant to bring to notice an error or a defect. They could be applicable to a company or an individual, and they typically seek a redress or adjustment. They are generally descriptive with a formal tone that should express displeasure, but the tone should not be overtly angry. You should address the problem and try to offer a solution to rectify the situation. See the example complaint letter below.
