Welcome to our Support Community. We do not have access to customer accounts here, however, you can reach your personal Team of Experts (TEX) by dialing 611 or work with T-Force via Facebook/Twitter. One other thing to mention is that if you're looking at your bill through the My T-Mobile app, there should be a section under "Bill" that says "What changed this month?" then list the charges that were different from last month.
