Reviewing and revising your complaint letter is the final step in the writing process. You will check your draft in this step, making sure that your objective is clear and your scope is concise. Put yourself in the reader's shoes as you examine the rough draft. Ask yourself, as the recipient, whether you are able to comprehend the request quickly and if enough information has been included to enable a timely response.
Look for the obvious errors first. Check for spelling, sentence structure and grammar mistakes. Remember that a passive voice is not as commanding as an active one. You want your letter to be strong, so write with an active voice.
Keep in mind is the overall cohesiveness of the whole unit. Look for accuracy, clarity and a sense of completeness. Ask yourself if the transitions between paragraphs are working and if your point of view, tone and style are consistent throughout the text.
Examine your word choices carefully. Ambiguous words lead to confusion. Jargon and abstract terms may not be understood at all and affectations, clichés and trite language serve no real purpose and will obscure your objective. You want to help your reader understand exactly what it is that you want, so remove all that is not helpful.
And finally, if you have not written an opening or a conclusion now is the time. The introduction needs to lead into the body of your letter with a firm statement about the subject of your complaint and enough supporting information to keep the reader reading. Your closing remarks need to reiterate your objective with a question that calls for an action.
As shown in the sample complaint letter, the writer' opening paragraph states the problem and the closing paragraph requests a specific solution.
