Start Preparing My ComplaintFrequently asked questions
How do I complain about wrong billing by my mobile operator?
First raise a complaint through the operator's app, helpline, or SMS. Note the complaint ticket number. If not resolved within 30 days, escalate to the Appellate Authority (details available on the operator's website) and then to TRAI or TDSAT.
What proof should I keep for a telecom complaint?
Keep your bill copies, balance deduction SMS notifications, screenshots of your service plan in the operator's app, customer care ticket numbers, and any written communication from the operator. Balance deduction SMS records are particularly important.
Can TRAI help resolve my telecom complaint?
TRAI sets regulations but does not directly resolve individual complaints. The Telecom Disputes Settlement and Appellate Tribunal (TDSAT) handles specific disputes. Start with the operator's Nodal Officer, then the Appellate Authority, before approaching TDSAT.
What mistakes should I avoid in a telecom complaint?
Do not rely on verbal commitments from customer care — always get a ticket number. Do not wait more than 30 days before escalating. Keep all SMS notifications about balance changes. Always ask for a credit or reversal in writing, not just a verbal promise.
