Quick Reply: Telecom complaints have a fixed ladder: operator first with a docket number, then the appellate authority, then TRAI. Skipping a rung wastes time.
Direct answer. Telecom grievances only move when you have a docket number from the operator, because every later stage asks for it. Fraud reporting is a separate track through the government's Sanchar Saathi platform. The guides below keep those two tracks apart.
If a department has the record you need and will not hand it over, an RTI application is the route that forces the question. Start with the RTI application format, and if the reply does not come or does not answer, the first appeal is the next step.
