Most companies do want to hear what you have to say, both good and bad. You must act on the assumption that they will try to take action based on your input. So, when you are writing your letter:
• Know the dates and locations of the incident
• Know the names of any people involved
• Describe the incident (try to keep it short, details are important, but this is not a novel!)
• Express in succinct wording why the incident was unsatisfactory to you
• Express what steps you would like taken to rectify the problem
If you leave the letter open-ended, the recipient may not know what you need/require to satisfy you. Then you may be left more unsatisfied because they did not take the steps you believed necessary to fix the situation. So let them know what happened, how it affected you, and what you would like to see happen to rectify the situation.
