We traveled to France in April so I added the $100 per month share to three lines. As soon as we returned I canceled the plan on the Verizon website. We have not traveled outside of the U.S since so obviously we are not using the international plan,.The next month I was still charged $300 more than usual. This has gone on for months despite frequent calls to customer service during which I was assured the charges would be removed from subsequent bills. And now it's August and the extra charges remain on my bill!
