I too am having UNEXPLAINED DATA USAGE problems. I have now spent a total of 6 hours on the phone with exede just going in circles. Still no one can explain how we could have used 31.6GB of data between 12am-5am on a single i phone that no one was using. They have spent hours trying to tell us that the kids were streaming but we live in a 1 room building and no one was up the night 31.6 GB were used. I wouldn't even know how to use that much data. We have been on the 150GB plan and regularly use 80-90GB per month. They DO keep insisting we consider changing our service to a new plan with a new 2 yr. contract which we don't want to do. Last Friday the service rep gave us 16GB. Before I went to bed we had used .8GB but at 7am all 16 GB were gone and it all happened between 12-5am when we were NOT ON the internet. We are very frustrated and working on a complaint to the Public service commissioner now. I see on this board that others have had similar issues. Has anyone had any real luck in dealing with it? Are there any other legal resources to consider?
