@ismail_killerWell, as far as im aware things dont add up.
How come you're using same account but you never linked your console account to the current EA account? Isn't it linked by default?
Now regarding all of this, assuming you actually have only one EA account (which im very sceptical due to what you wrote) then It shouldn't be a problem.
BUT
If you actually have 2 EA accounts (one for PC, one for Console) then sadly merge won't be possible.
