Reliance Jio Infocomm — reliance jio data usage

Address:

712101

Reiance jio is showing fake data usage. I've a connection with daily 1gb data limit. It starts with good speed in the morning but after about 1 hour of browsing or so, it says 1gb limit is over. I'm just browsing without even downloading any files. The actual data usage is hardly more than 200mb. And this is happening every day.
The jiofi device is password protected and there is only one connection which i can confirm even from the default web gui.
Every time i call their customer care, they are disonnecting the call midway adding to the frustration.

Thanks
