Data usage doesn't match phone

[jac509]

Over the past couple of months, I've noticed an issue with high data usage. In order to determine the cause, I've disabled some apps and starting tracking usage with the built-in iPhone app. My cycle recently restarted and I recieved an alert a couple days after saying that I had used 6+ GBs of data. My iPhone all shows 400 MB of data use during that time period. I have reached out to chat and phone support they have not been able to help. It seems Xfinity is having trouble keeping track of data usage or the iphone is not tracking correctly. I did have it happen with my other line last month but didn't have any proof, but now I do. Has anyone seen this issue?
