I'm really sorry you're stuck waiting. The best thing you can do to speed up the process is to create a support ticket. It's possible that it's something specifically affecting only a few people, and they won't be able to figure out what until they have data from some of those affected. It's possible it's a series of coincidences affecting people differently, so again, they need to know your specific situation. I tried to get a couple friend to see if they could do it (one in Europe, one on NA) and they both have the exact same issues - the redeem button won't allow them to redeem it and the language option won't allow them to select a language. I don't think the problem is specific to only a handful of random people.
