Hi LeemHanSeong,

I am sorry to hear that you have not received your key. Unfortunately we have currently run out of keys for this game but we do have more on order which will be with us very soon.

I have processed a refund for you which should be visible in your account within 2-3 days, if not sooner. We should have more in stock later today and I would encourage you to make the purchase again. Due to the system we're working with we cannot simply add the key to your account in this instance.

Apologies for any inconvenience caused.

Regards,

Sam
