Formal Complaint Letter Writing

Introduction

In our last lesson, you learned how to structure a formal letter of request or application, focusing on a clear purpose statement and developing each bullet point into a full paragraph. This foundational skill is essential for any formal letter in Writing Task 1.

Today, we will adapt that knowledge to a different, but equally common, task. The learning outcome for this lesson is to write a formal letter of complaint using appropriate tone and structure. While the overall structure remains similar, the key to success here lies in mastering the specific tone and vocabulary needed to complain effectively—that is, to be firm and clear about the problem without sounding rude or overly emotional.

1. The Structure of a Complaint Letter

The good news is that the structure for a formal complaint letter is almost identical to the one you've already learned. The main difference is the content and purpose.

Let's start with a video that breaks down how to approach an IELTS complaint letter question, from analyzing the prompt to planning your response.

As the video explains, the core structure is:

1. Greeting: Dear Sir/Madam, (when you don't know the person's name).
2. Paragraph 1 (Purpose): State your reason for writing (i.e., to complain).
3. Paragraph 2 (Body): Address the first bullet point.
4. Paragraph 3 (Body): Address the second bullet point.
5. Paragraph 4 (Body): Address the third bullet point.
6. Sign-off: Yours faithfully, followed by your full name.

This systematic approach ensures you cover all requirements of the task logically.

2. Mastering the Language of Complaint

The most significant new skill for this lesson is learning the specific vocabulary for complaining formally. You need to express dissatisfaction and request action clearly and politely. Using the right phrases is crucial for achieving the correct tone.

The following resource provides an excellent bank of phrases for each part of a complaint letter.

Here are some of the most useful phrases from that resource, categorized by their function:

• Stating your purpose:
  • I am writing to complain about...
  • I am writing to express my dissatisfaction with...
• Introducing the problem:
  • The first problem was that...
  • My first concern is...
• Adding further complaints:
  • In addition to this...
  • To make matters worse,...
• Demanding action/proposing a solution:
  • I would therefore like to request that...
  • To resolve the problem, I would appreciate it if you could...
  • I suggest that you replace the item.

A key tip: Avoid emotional or aggressive language like "I'm furious" or "This is a disaster." Stick to formal, objective phrases like It is not acceptable that... or I am disappointed because....

3. Analyzing a Model Complaint Letter

Now, let's see how these elements—structure and vocabulary—come together in a finished letter. We will look at the sample letter from the IELTS Jacky website, which is based on the same prompt from the video you watched earlier.

Here is another visual example of a well-structured complaint letter. Notice the clear paragraphing and formal tone.

4. Practice Exercise

It's time to put your knowledge into practice. Please write a formal letter of complaint based on the prompt below. Remember to plan your ideas for each bullet point before you start writing. Aim for at least 150 words and try to complete the task in around 20 minutes.

Prompt:

You recently ordered a new office chair from an online furniture store. When it arrived, you discovered several problems with it.

Write a letter to the store's customer service manager. In your letter:

• Provide details of the order you placed.
• Describe the problems with the chair.
• Explain what you want the store to do about the situation.

Once you've submitted your letter, I will give you feedback on its structure, tone, task achievement, and grammar.

Conclusion

Today, you've learned how to apply your knowledge of formal letter writing to the specific task of making a complaint. By combining a clear structure with appropriate, formal language, you can write a powerful and effective letter that will score well on the IELTS test.

Key Takeaways:

• A letter of complaint uses the same 6-part formal structure: Greeting, Purpose, 3 Body Paragraphs, and Sign-off.
• The tone should be firm and clear, but always polite and formal. Avoid emotional language.
• Use specific vocabulary to state your complaint, describe the issues, and request a clear resolution.
• Ensure each body paragraph fully develops one of the bullet points from the prompt.
