Unable to charge nx via credit cards

I have this issue aswell. I sent a ticket about it, and the gm said they have a new verification process for finding players who hack the free surveys or use fraudulent programs to complete surveys. But as always, please will end up falsely accused. Your account will be rescricted from paypal or buying nx from a credit card. It sucks, since I don't know how to use pay by cash. And, just to my luck, no stores near me sell nx cards...
