Reliance Jio — data over calculating

Address:

Peenya Bengalur, Bangalore, Karnataka, 560058

Sir,
I am using jiofi device to my mobile for wifi connection. I activated 1.5 gb per day data plan but when i cross 350 mb i'll get message from jio i had completed my 90% data of the day. Customer care not responding for this issue and don't take complaint.
I have checked data usage in mobile and also internet speed meter application.

Please take action on this issue.
Thanks you
