If you are from a Tier-1/Tier-2 city, be prepared for further delay in resolution. You can try escalating it via twitter. You can also visit the nearest Jio Store and get the FR lead's number, try contacting them directly. My airtel fiber connection went down last week and i tried this. While most issues take 7-10 days to get resolved in my area, it took them somewhere around 48 hours to fix my issue(some optical power issue and a fiber cut) when i called the FR(fault resolution) technical lead. Keep your ticket number ready before calling them.
