I redeemed specialization code on wrong acct

I received the email with the codes. I clicked on the link, it automatically signed me in to what I thought was my x box live account. I redeemed the code (this is all through the computer). I later found out it was on an account that no one uses, I’m not entirely sure how it even signed me into that account (it was an account made accidentally when trying to redeem my halo helmet avatar thing we got a while back). I wanted to know if there was a way that I can get this code for my real account or if I’m completely screwed. Thanks

Maybe through license transfer?

What is a license transfer and is it something that I can do personally or is it something tech support would have to do?
