Reliance Jio Infocomm — Low speed and signal

Address:

Bijnor, Uttar Pradesh, 246763

Dear Sir / Madam
Myself Javed khan an user of Jio Prepaid service.
My Jio no. is: [protected]
I am using Xiomi Redmi 2Note

I am using this connection since last 2 months.
From few days I am getting a very pathetic network in a particular location in outdoor and indoor coverage and also I am getting a very poor 4G speed (in a particular location).
I am getting 0 to 1 signal bar, sometimes it's showing "No Network"/"Emergency Call Only" when I am in indoor coverage and in outdoor coverage some times it's showing 1 (maximum) to 3 signal bar and also some times it showing "No Service"/ "Emergency Call Only".
Not only me, some of friends are also getting same experience like

I have complained many times to resolve my problem &
Customer care told me that it will take max to max 48 hours to resolve.
After 48 hours when I called up to the cust. care that my complain has not been resolved, on that time they raised a complain and again they were assured that it will take 48 hours to resolve my complaint. But alas ! I am still facing the same experience.
