Reliance Jio Infocomm — no range in my locality

Address:

North Goa, Goa, 403521

I am residing at housing board, mapusa, goa.
Ever since i have taken a jio sim i'm not getting range in my area. The signal strength is very poor.
Due to this internet speed is very slow and calls cannot be made.
Despite numerous complaints my problem is not yet solved.
It is not only i who is facing the issue, jio data connectivity issue is faced by many people in my locality.
Reliance please look into this and solve it at the earliest.
