Reliance Jio Infocomm — unclear usage of data

Address:

Chandigarh, Chandigarh

I have a complaint regarding the Unclear usage of jio data . From 3 days I have been noticing that my whole 1.5gb jio data is being consumed at night between an hour. And strange thing was that my phone was in my pocket and there were no background apps working and no hotspot on at that time . I called jio customer care and they told me that there would be any background apps running but they were not. So please help me to get rid of this problem. And strange thing is that if there might be any background apps running, how can they consume 1.5 GB data in less than an hour. If anyone reads this complaint please tell me how to Port from jio to Airtel.

Thank you
