Can't buy a Carbon coupon

I can't buy the 150 point Carbon freeroll coupon. I've tried twice. I double checked the screenname and made sure it was my Carbon account. But each time I buy the coupon, I get rejected. And then when I check the screenname, it shows my PokerOwned.com screenname next to my Carbon account. That is strange, because before I bought the coupon, it was my Carbon screenname there.

Has anyone else had this problem? Any suggestions for should I do?

I have not had that problem, nor have I seen it commented on in the forum (granted, I usually am only reading the forum for about an hour each day). I would suggest contacting one of the mods to describe the problem you're having. Maybe see if one is active in the chat room.
