I have lodged a grievance. How long does the Sarkar usually take to respond?

Quick answer: Most grievance systems (e.g. CPGRAMS, State portals) promise an acknowledgment within a few days and resolution within 15–30 days for many routine civic issues. Complex issues may take longer. The portal or acknowledgment slip usually shows the expected timeline. If you get no response by that date, use the escalation or first-appeal option.
