serial code from steam has been exchanged

Hello, 

I need help to fix an issue with my account. I haven't used Origin to play my games, in fact I don't have games in Origin. I mainly use Steam, but now that I was in need of using it, it has shown a problem.

The thing is that I have Spore registered in Steam, I tried to add the game to Origin but it says the code has been exchanged, I checked in my two accounts of Origin (I had registered with my two emails for some reason, I wish it was only one) and the game is not there. So I think I may have been hacked or something and want to fix that problem, I have proof of being the legitimate owner of my game and I want to add it to Origin so I can play Spore with all the features that I don't have in Steam.

Please help and thanks

P.S: I'm reporting this as a problem since I've seen people having the game both in steam and in Origin at the same time with the same code.
