If notice pay has been wrongly recovered from your salary — you served your full notice, the amount is wrong, or the deduction was never intimated — collect your payslips, appointment letter, resignation acceptance and final settlement statement, and send one precise written complaint to HR or payroll asking for a refund of the wrongly deducted amount. Ask for a written reason if the request is refused or kept pending. Escalate with the same evidence bundle to the authority appointed under the Code on Wages 2019 (often the Labour Commissioner office of your area), and to EPFO through EPFiGMS if PF money has been touched. Use RTI only for records held by a public authority: with a government employer, file movement, deficiency notes, dispatch records, sanction details, payment advice, inspection reports or reasons recorded on file.
Use the correct external forum. Use EPFO or the other official source linked below where it fits the subject. For consumer-service disputes, consider National Consumer Helpline and e-Daakhil. For public departments, CPGRAMS, state grievance portals and RTI may help. For high-value or time-sensitive cases, take professional advice before limitation expires.
Use a legal notice when the amount is high, limitation may expire, the other side is ignoring written complaints, or a contract right is being denied.
