Being able to keep track of your data usage through the My Verizon application is a must, and I'd be glad to help figure out what's going on with the usage not updating properly.
First, to make sure I'm on the same page, are you using the My Verizon application or the web page itself to view the information? What happens if you view the information on your computer or laptop versus the application (sign in here: http://spr.ly/6608EU4Hm)? If you have others on your account, what happens if they access the data usage tool on their device?
We'll be standing by to ensure you are set up for success.
