here's the link for reloading prepaid cards =)
There's two boxes to fill in,
- one is the security check box where u fill in the charcters displayed in the image below (the link to the right of the image generates you a new code incase you cant see the first)
- the second box is where you input the reload card number.
When you're done doing that, click the RED button to check the details and select your server which you're adding to.
hope this helps! =]
