When and How to Write a Complaint Letter to a Business?

• If a phone conversation doesn’t resolve your issue, consider writing a complaint letter to the business.
• Focus on the specific problem with the product or service. Avoid unrelated complaints.
• Gather all relevant documents, such as receipts, warranties, and guarantees.
• Include essential details like the product's brand name, model, essential details, and serial number in your letter.
• Always send copies of these documents. Keep the originals for your records.
