HI I faced the similar problem and logged a request at customer care.
Alternatively I have worked out a method to find the usage. I use Huawei Device
The downloads and uploads are logged in file \Reliance Netconnect\userdata\NetInfo.dat
It can be opened in notepad to view the log.
It can also be viewd via a NetInfoUIExPlugin which is disbaled. It can be enabled by changing Reliance Netconnect\config\PluginsConfig.xml
Uncomment line 57
i.e. Change line from '<!--item name="NetInfoUIExPlugin" clsid="AC7C3BF8-40C1-4b39-8B67-32F85E6B2E6F"/-->' to
'<item name="NetInfoUIExPlugin" clsid="AC7C3BF8-40C1-4b39-8B67-32F85E6B2E6F"/>'
Quit application and restart. The application will have a new tab now that will show all records.
Happy Surfing!!
