Jio Prepaid — everyday waste my data balance

Address:

Amman koil street perungappur, 604151

I had recharge my jio prepaid number [protected], last two weeks ago. Now coming to home locations. Indoor I have open Pinterest application .the application not open full loading.
My recharge amount is everyday waste.
Main reason no network coverage.
This is real situation but jio network is saying high speed data 2Gb per day

I had complaint many times (approximately 30times)customer service is saying, we will correct this problem some days .
But No any improvement this problem .
