The Complaint Letter For Sim Card Not Working is a formal document used in the Indian telecommunications sector when a customer experiences issues with their SIM card service. This document type is essential in the Indian jurisdiction, where telecom services are regulated by TRAI and consumer protection laws provide specific frameworks for grievance redressal. The letter should be used when standard customer service channels have failed to resolve SIM card issues, serving as an official record of the complaint. It includes essential details such as customer identification, service details, problem description, communication history, and specific resolution requests. The document follows TRAI's consumer complaint guidelines and can be used as evidence in escalated disputes or consumer forum proceedings.
