Reliance Jio — network issue problem for reliance jio telecom service

I choose the jio network and recharge with 398. But i do not get proper service from jio. All the time jio network is too slow thats not usable. When i call to jio customar, they told me that they have to take 60 days to solve this problem. After 60 days the problem is restart, now jio telecom service tell me they have to take above 90 days too, i think jio is fraud with us.
So, i request to trai, please give a step against reliance jio service.
