Im still waiting for NCsoft to reply about switching my keys, 2 full days and no response yet 
I made it easy by sending all the information they would need in one email, old key number to remove, new key number to apply, and a screenshot of my direct purchase receipt and paypal transaction.
So all they have to do is remove the old key and apply the new for me, once they bother to read the email.
