Same here, Visited Verizon store and wife bought an iphone 6. Data spiked 4GB across two phones over a 3 min period, one was not in use at the time. Verizon is not going to be able to tell you details on what specific sites were involved with the data spikes. You will need to take a ride down to your county courthouse and get the required paperwork to subpoena your data records. Submit the paperwork and you will receive a call from Verizon's legal dept and tell them what days you are looking for. You should have the reports in your hands in a week or so.
