I've emailed Nintendo to try and establish when codes were activated. Once I receive everything back I'm going to put a claim in against the buyer to say item is no longer sealed and in a used condition as re-sale value will drop now. He's obviously trying to get £70 back off me. Sad thing is he accused me of being a bad seller and a lier. I know everything was sealed, I have the photo to prove it. He also had the cheek to leave positive feedback by saying everything is excellent
