Reliance Jio Infocomm — internet speed and call quality

Website:

Jio.com

I contact to jio customer care for several times for poor network coverage. the internet speed is very poor and call quality is very bad in my locality beacause of the network coverage. I contact jio customer care for 8 months or more but each time they say that it will be fixed in 180 days or 90 days.but the issue yet not fixed.so take some action.
