How to Write a Complaint Letter Format

Complaint letters are written to the appropriate authorities when you are dissatisfied with a service or have a problem that needs to be resolved. A complaint letter should be written in the same structure as a formal letter; nevertheless, do not forget to be polite. To compose a complaint letter, begin with the sender's address, then the date, the recipient's address, the subject, salutation, body of the letter, complimentary closing, signature, and name.

Students should follow the guide below to gain a thorough understanding of the process of creating a complaint letter, including what should be written where.

SENDER'S ADDRESS- The sender's address is typically displayed in the top left corner of the page.

DATE- The sender's address is followed by the date, which appears directly below it on the left side of the page. This is the date on which the letter is written. It should be written in extended form.

RECEIVER'S ADDRESS- It is up to the writer whether to include "To" above the address. Make sure the first line of the address includes the receiving official's title/name/position, etc.

SALUTATIONS - This is where you greet the person to whom the letter is addressed. Keep in mind that this is an official letter, so the greeting should be respectful but not overly personal. Formal letters utilise the usual greetings "Sir" or "Madam".

SUBJECT- Finally, we summarise the purpose of the message in one line. This allows the recipient to focus on the subject of the message at a glance. It is critical to highlight the subject.

BODY- This is the main content of the letter. It is either divided into three paragraphs or two paragraphs if the letter is briefer. The tone of the content should be formal. Do not use any offensive language. Another point to be kept in mind is that the letter should be concise and to the point. And always be respectful and considerate in your language. It should include-

• Short introduction paragraph- Provide details about the product or service that is the subject of the complaint. Include dates, location, and the specifications about the item or service.

• State the issue with the item or service. Provide details as to the cause. This may include malfunction, billing issues, details that were not disclosed, etc.

• Indicate how you would like them to resolve your problem. Provide specifics about what you’re seeking.

• Indicate that you are including copies of the transaction document.

• Indicate that you look forward to their reply within a specific time.

• Indicate that they can contact you about the issue and provide your contact details

COMPLIMENTARY CLOSE- At the end of your letter, we include a complimentary closure. The terms "Yours Faithfully" and "Yours Sincerely" are used.

SIGNATURE- Finally, sign your name. Next, write your name in block letters beneath the signature, followed by your designation. This is how the receiver will know who sent the letter.

 

Tips for Writing an Effective Complaint Letter

Start your letter politely

Manners are highly important. Cordial letters (warm, friendly, gracious, or sincere) are more likely to be received and read. Letters containing threats and all uppercase, on the other hand, receive the bare minimum of response. Or not at all. 

If your letter contains profanity, it will most likely be ignored, and those that are deemed threatening will be turned over to law enforcement.  The most effective e-mails and letters are short, averaging only 500 words.  They offer all of the information needed to track your situation.

Ask a question

Your request should be formatted as a question. The query should be along the lines of "How do you fix this?" State exactly what you want done and how long you're willing to wait for a response. Another common phrase pattern is "I wish to complain in the strongest terms about". The question should be straightforward to understand. It also helps if it is genuine and without sarcasm.

Explain the problem

You should mention your motive for writing the letter. Highlight the facts, such as the time, date, and location of your transaction or receipt of services. The reader should be able to get the point on reading the first few sentences; hence, it is important not to beat about the bush. Explain yourself well and be detailed to capture the reader’s attention.

Don't blame the individual you're dealing with

It is important that you maintain a courteous tone throughout your letter. No matter how justified your complaint is, your letter should not become angry, sarcastic, or threatening. Keep in mind that the individual who receives your letter is often not the person who actually caused the problem.

Show them you are in the know

If you can convince the company that it did not follow its own standards or disobeyed the law, your complaint will have a better chance of being heard. If your complaint letter does not result in the desired effects, consider writing another letter in a firmer tone or writing to someone higher up in the chain of command.

 

Complaint Letter Samples

A complaint letter format will typically start with the sender's information, followed by mentioning who it's addressed to, the date, and then the letter itself. The opening paragraph should state your reason for writing, and the core of the subject will go into detail about the matter. At the end of the letter, make it clear what you hope to achieve, and politely sign off.
