I've got refunded. It was 960 for the full price and 624 for the discounted one. It should have been 336 gems, but I got 317, since this purchase was done via gold to gems, maybe they calculated the difference on the fluctuating conversion rate? No idea, well I guess it's something. Just reporting, not complaining, I'm fine with it since the difference is minimal and no money were involved on my part this time.
