@a_savucin It sounds like you received a language-locked version of the game. There's nothing you can do to "convert" this to the global version, even buying more content. What you could do is get this version removed from your Origin account and buy a physical or digital copy from a retailer that offers the global version (be sure to read the fine print), then register that to your account.
Or you could buy the game from Steam, which as far as I've seen offers the global version to everyone. Test right away so that if you're still seeing the language-locked version, you can get a refund from Steam.
