The Complaint Letter For Defective Product is a crucial document in Indian consumer protection framework, designed to formally address issues with faulty or substandard products. This document becomes necessary when a consumer discovers defects in purchased goods and needs to seek remediation from the manufacturer, seller, or service provider. It serves as the first formal step in the consumer grievance redressal process under Indian law, particularly the Consumer Protection Act, 2019. The letter should be used after discovering a product defect and preferably after initial informal attempts to resolve the issue have been unsuccessful. It typically includes detailed information about the product, nature of the defect, purchase details, previous communication attempts, and specific demands for resolution. This document can later serve as evidence in consumer forums or legal proceedings if the complaint remains unresolved, making it essential to include all relevant details and maintain a professional tone throughout.
