Step 1: Gather Your Facts

Before drafting your complaint letter, ensure you have all the facts together. This includes gathering any documentation or other evidence that can support the claims made in your letter. You should also include contact information such as names, dates, etc., so it’s easy for the recipient to get back to you if needed.

Step 2: Start With a Professional Salutation

Begin your letter with the proper salutation. Address it to the correct person or department, making sure to use the recipient’s full name and title if possible.

Step 3: Explain Your Problem Clearly

In this section of your complaint letter, explain what happened and why you are disappointed or unsatisfied. Provide evidence, such as receipts, photos, etc., that support your claims. Make sure to remain professional throughout the entire letter, so you don’t come across as aggressive or demanding.

Step 4: State Your Desired Resolution

Let the company know what course of action you would like them to take to resolve the issue. Be specific and provide a timeline.

Step 5: Close Professionally

Conclude your letter with a professional closing, such as “Sincerely,” followed by your name, signature, and contact information.
