Complaint Letter to Telecom Company India

iGuideline Summary

Telecom service providers in India — including Reliance Jio, Airtel, Vodafone Idea (Vi), BSNL, and others — are licensed by the Department of Telecommunications (DoT) and regulated by the Telecom Regulatory Authority of India (TRAI). Consumers have enforceable rights under the TRAI (Quality of Service) Regulations and the Telecom Consumers Protection and Redressal of Grievances Regulations, 2012. Every telecom operator is required to have a tiered consumer redressal mechanism. The first tier is the operator's customer care, which must resolve your complaint within 3 days for general issues and 7 days for technical issues. If unresolved, you can escalate to the Appellate Authority within the telecom company (second tier). If the Appellate Authority does not respond within 3 months or gives an unsatisfactory response, you can file with the Telecom Consumer Complaint Redressal Forum (TDSAT — Telecom Disputes Settlement and Appellate Tribunal) or file a consumer forum complaint. TRAI also has a consumer portal — TRAI Connect (formerly the CPGRAMS telecom portal) — where you can register complaints against operators. Additionally, you can use the DoT's Sanchar Saathi portal (sancharsaathi.gov.in) for specific issues like SIM fraud, mobile theft, or incoming call blocking. Common telecom complaints include: wrongful or inflated billing, internet speeds significantly below the advertised or subscribed plan speed, arbitrary service disconnection without notice, failure to port your number (under Mobile Number Portability), unsolicited commercial calls (DND violations), value-added service activation without consent (deducting balance), SIM card swap fraud, and refusal to process connection termination requests. An effective complaint letter to a telecom company must include: (1) your mobile number and account ID; (2) the exact issue — billing discrepancy, speed, disconnection; (3) the plan you subscribed to versus what you are receiving; (4) dates and reference numbers of previous complaints; and (5) the specific relief you seek — billing correction, refund of deducted amount, or service restoration. GetNyay is India's AI complaint letter drafting platform that helps you generate a structured telecom complaint letter, which can be submitted to the operator, TRAI, or used as the basis for a consumer forum filing.

When to File This Complaint

• Telecom company billed you for a plan upgrade or value-added service you did not authorize
• Mobile data speeds are consistently below the speed guaranteed by your subscribed plan
• Service was disconnected or suspended without prior written notice or valid reason
• Mobile Number Portability (MNP) request was rejected without valid grounds
• Do Not Disturb (DND) registration is not being honoured and you are receiving spam calls
• Balance was deducted for a value-added service you never subscribed to
• SIM card was swapped or new SIM issued against your number without your consent

Documents Required

• Mobile number and account details (SIM number, account ID)
• Most recent bill or recharge receipt showing the disputed charge
• Screenshots of TRAI MySpeed app reports showing actual speed vs. promised speed
• Screenshots of customer care chat logs or complaint reference numbers
• Recording or screenshot of unsolicited commercial calls (for DND violations)
• Written request for MNP or service termination and operator's rejection (if applicable)
• Any written communication from the telecom operator regarding the issue

Common Mistakes to Avoid

• Not recording the customer care complaint reference number — required for all escalations
• Filing with TRAI without first completing the operator's two-tier grievance process
• Not using the TRAI MySpeed app to document actual internet speeds before complaining
• Accepting a one-time billing credit without getting the underlying billing error corrected
• Disconnecting the SIM or switching operators before the complaint is fully resolved
• Not specifying the exact amount of wrongful deduction in the complaint letter
