They have terriable pre-paid cards. I recently bought one for $25.00. When I scratched it off. Everything came off including my pin. I want to their forums under support and found that the link http://web.incomm.com/contactus.do didn't work. I smell scam. Poorly made prepaid cards + not working link. I did get a working link once I contaced them. Of course they gave me a working link and shoved the problem else where. I'm really glad it was only my first 50 hours of gameplay for me to figure it out. Stay away, FAR AWAY from prepaid cards. I just unistalled the game.
I know that everyone will have a different outcome with their problems. But I wanted to share mine. I had already given the company some of my money. But they do not care unless you're a top name in the game/fleet/guild. That's the only way to get help in these games. I was enjoying the game too. But having someone play your game is a privlage not a right.
