Poor customer service

To see which apps used your data, go to Settings - Data Usage (change usage cycle to display a specific day). Alternatively you can install ?My Data Manager? to help you identify programs using your data. Have a pleasant day further!</p> <p> </p> <p><strong>This explanation is a total copout of doing proper analysis and feedback on what is the real cause of the problem. I do not accept this explanation and would appreciate if someone could explain to me how an app can use previous cycle data when there was still existing data available. </strong></p> <p> </p>
