I am having the same issues here. I got my card about a week about for 3 months of premium and it wont redeem and I've already contacted customer support they said come here and at this point I'm just gonna have them redeem it for me cause it's been a week and it wont work. It keeps saying something went wrong or CSRF token is broken and I've used incognito and other browsers and devices. Please help me here I'm getting fed up.
