Reliance Jio Infocomm — wrong data usage: jio fraud

Jio calculates data usage wrong. I had recharged with 129 which gives 2gb of data a month. I also have broadband connection at home so i rarely use mobile data and 2gb is more than sufficient. Just after 3 days of recharge jio sends me message that you have consumed 50% of your data. The fact is that i did not even on my data on my phone. All this while i was using broadband.
To confirm this i opened my data usage in my phone (In built feature). It says 128mb only. You can check the screen shots.
This is clearly a very big fraud. And consumers are being cheated.
