I've had the same issue. EA Community Managers on these forums are telling us to contact EA Support and they will unlink the accounts for us, however I did this, and EA Support told me it is not possible for them to unlink them at all. So either 1 half of EA is completely misinformed or lying to us. I've gone back to support and asked if 2 accounts can be merged but I'm still waiting for a reply back. If that's a no dice, I'll ask them about deleting the EA account that has the link, and seeing if that will force a unlink. But at the moment we're stuck.
