Write about your problems to akash.ambani at ril dot com and see if it solved or not.
Once upon a time I wrote to sanjay.mashruwala at ril dot com and my network problem was solved by local jio network engineers by way of installing a outdoor small cell 50 metres across my residencial house.
You can also write to sanjay.mashruwala at ril dot com with attaching the mail as cc to akash.ambani at ril dot com. It would be even better.
Whatever you do make sure write a nice elaborate literature describing all your problems faced till date. Then there will be some action I think.
Wish you good luck.
