Dasffion is right, they charged only the pre-order fee.
*For "digital copy" buyers (like myself), you received an early-access code to redeem and play earlier (...)
*your purchase is much like to be as "pending" at origin´s web site, since the game launch will only happen next week, then you will have you activation code
SO... redeem your pre-order code (if you haven´t yet), play at early access (if you can); after game launch go to Origin´s website, grab your new official game code and redeem to activate the "official" game.
