for Virgin issues:

I suggest you file acomplaint with Indiana Utility Regulatory Commission (they oversee telecommunication companies such as Virgini Mobile). Trust me, this usually gets you a very swift response, as the State will get involved - and no company wants to be on their bad list!

Local phone 317-232-2712 or toll free 1-800-851-4268

here is the web address to file a complaint online:
