It formally notifies businesses (e.g., telecom providers or e-commerce platforms) of your grievance, often prompting quick resolutions before escalating to consumer forums. 

Under the Consumer Protection Act, 2019, a clear letter with evidence strengthens your case, whether for a refund or replacement. 

It’s the first step in dispute resolution, saving time and effort and is effective across India, from urban centers to rural areas using platforms like NCH.

Structure of a Consumer Complaint Letter

A well-structured consumer complaint letter includes:

1. Salutation:
   • Address the recipient professionally (e.g., “Dear Customer Service Manager” or “To [Company Name] Consumer Affairs”).
   • Use specific names if known (e.g., “Dear Ms. Sharma”).
   • Tip: Avoid generic greetings like “To Whom It May Concern” for better impact.

   • Details of Purchase: Include product/service details, purchase date order number and cost.
   • Problem Description: Explain the issue clearly (e.g., “The phone I ordered is defective”).
   • Resolution Sought: Specify your desired remedy (e.g., refund, replacement).
   • Supporting Evidence: Mention attached documents (e.g., receipts, photos).
   • Timeline: Set a reasonable response deadline (e.g., 10 days).

3. Closing:
   • Restate your request politely (e.g., “I hope for a prompt resolution”).
   • Provide contact details (e.g., email, phone).
   • Sign off professionally (e.g., “Sincerely, [Your Name]”).
