Sadly the "no return" policy of most stores of open games may cause an issue, even more sad is you have waited 3 days and it seems I am the (second) person to even look at this. This is going to be very difficult to return the game. I would say the best you can do is try to open a case with EA through their request system, sadly I have been trying for weeks to get answers from EA and its affiliates, and everyone seems to not exist. I wish you the best of luck in this seemingly impossible endevor, just know others feel your pain. I am sorry you have to deal with this.
