Multiple Accounts & trying to link them

Hey I have an account for Madden NFL mobile, on my iPhone a basic one without logging through facebook. I recently got a iPad and wanted to connect the games, however have already created an account through facebook on my iPad. Was wondering if there was a way to merge the two accounts, especially since spent money on both accounts. Or at least if there is a way to send myself my cards from one account to another. 

Thank you any ideas are appreciated.
