Regarding the promotional voucher given out during the Semi-finals

Hello, just wondering, has anyone else received the Fnatic championship skin voucher for attending the semi-finals in Seoul?

The card that they give out states that you have to go to https://signup.leagueoflegends.co.kr/skincode and fill the form out there in order to redeem the code, but when I hit submit to finish the form, nothing happens. It just stays on that same page.

I've contacted customer support regarding this, too, but I got an e-mail back stating I need to contact the Korean customer support for the issue despite the fact that the website states I should "contact Riot Player Support for respective regions". Doesn't help I don't have a Korean account, so I can't access their customer support page..

Would appreciate any insight on this issue,

Thanks.

EDIT:

Never mind, managed to redeem it. Apparently you need to use internet explorer for it or switch to Korean language.. The confirmation screen stating your voucher has been redeemed doesn't come up otherwise. So anyone else looking to redeem their skins from going to the championship events, be advised.
