A complaint letter is a formal document used to express dissatisfaction regarding a product, service, or experience. It serves to:

  • Inform the concerned party about the issue

A well-written complaint letter increases the likelihood of a satisfactory response.

Before drafting your letter, collect:

  • Company or recipient’s details
  • Date and location of the incident
  • Description of the issue
  • Any previous communication regarding the complaint
  • Supporting documents (receipts, photos, or emails)

3. Maintain a Professional and Polite Tone

Even if you are frustrated, your letter should be polite and factual. Avoid aggressive language, threats, or emotional statements.

4. Start With a Clear Opening Statement

Begin your letter with a direct statement about your complaint. Example:

“I am writing to formally raise a complaint about [product/service/experience] that I purchased from [Company Name] on [Date].”

5. Describe the Problem in Detail

Explain the issue clearly and concisely:

  • What happened?
  • When and where did it occur?
  • Who was involved (if applicable)?

Example: “On [Date], I purchased a [Product Name] from your store. Upon opening the package, I noticed that it was damaged and not functioning properly. Despite reaching out to customer service, the issue remains unresolved.”

6. Provide Supporting Evidence

Attach relevant documents such as:

  • Receipts or invoices

“I would appreciate a response within 10 business days.”

9. Include Your Contact Information

Provide your:

  • Name
  • Address
  • Email
  • Phone number

This ensures they can easily reach you.
