JioFiber customer support is pathetic, I've heard many incidents. In my case, the router isn't connecting to 2.4GHz, I called customer support on 11th, today is 15th. Nothing has happened. They did they'll replace the router, but nothing. No one picks calls. The local guy who called me isn't picking up for 3 days. Thankfully I'm in this free trial period, if they don't do something in next couple of days I'm asking for my ₹2500 back.
