Why do i have 2game center accounts on my one apple id and how do i login to the other one.

Title says it all. All my game data that i earned and paid for are gone and i apperantly have two game center accounts according to this apps support team. When i try do disable the bad account it doesnt work and when i try to change the apple id it says "that apple id is already in use" even though i just made it. So how do i log into the right account?
