Which phone model do you have? Which plan do you have?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
Not sure why you put this in the windows phone discussion. Your phone should tell you which apps are using data and how much. Verizon is not mysteriously taking data away.
Assuming you have one of the plans that have come out in the last 2 years you can enable safety mode and you wouldn't have overages. Of if not on one of the newer plans you should probably move to them as they would most likely be cheaper anyway and give more data.
Nobody here wants you to leave, Armygr78. Boringusername has a fantastic suggestion to get to the details of what is using data. On Windows Phone that is called Data Sense, and here is how to located it.
