The screenshot below show that Verizon log data activities from 07/22/14 from MyVerizon Data Usage.
The screenshot below show data usage from the device corresponding the schedule above.
From 07/22/14 up until now (07/28/14), there is "MO MOBILE DATA ACTIVITY" and the mobile data is "OFF" for a weeks.
Overall data usage from the beginning of this billing cycle show 173MB, but on MyVerizon show 689.84MB as shown on two screenshots below.
After talked to Verizon at local store, he could not figure out what really happen.
He called a Verizon's technician on the phone to see data activities.
From technician view, his information from three sources are not agree with each other.
The data usage session log show NO ACTIVITY since I turned of the mobile data.
There is no established connection between my device and their server for a week.
The billing system log activities as shown on first screenshot.
While I am at Verizon store, their staff turned off mobile data and use it via store WIFI. The billing system accumulate about 4M in just ONE MINUTE.
I decide to do an experiment by REMOVING SIM CARD from device and leave it with local Verizon store. I will heavily use the data VIA WIFI until the end of this billing cycle. If the billing system log any activities, there must be some flaw in Verizon system. If not, there must be some BUG in the device's firmware.
But for now, Verizon customer service must stop thinking that the mistake is only from user error, and start looking on your billing system.
P.S. Technician on the phone offered me some amount of free data allowance, I am gladly accepted the offer. BUT it would be useless if the problem cannot be pin pointed.
