Even if it is not an original, you could try to exchange it to the shop (not to Square Enix,)
If they insist that you cannot exchange it, next time DO NOT buy from that shop or any other shop which is HARD to EXCHANGE.![]()
Believe me, it is a bitter experience if you buy from that kind of shop.![]()
If you cannot find a shop which is easy to exchange, then... just buy the original one.![]()
