If the normal way does not work (clicking the gold icon then selecting CC and the amount you want etc) then you can e-mail the support team and they will place an order through for you on the spot.

You can contact probiller directly on skype. Good luck.
Or if you have seperate card (like me) you can throw your card number to probiller directly.
They will do all billing for you (strongly not recommend).
only nigerian princes are trustworthy enough to send financial information to over the internet
Huh I don't even see a paypal option. I had an issue paying with CC so I had to contact the biller to attach my card.
