よくある問題I'm getting this error when trying to claim a 15th Anniversary key over my Alabaster Mounts
Many of you who plan on purchasing a physical Collector's Edition version of our games are also interested in the benefits you get from pre-purchasing digital goods included in the Collector's Edition. To help with that, we may credit you the cost of the pre-purchase version in Battle.net Balance directly to your account when you later claim the Collector's Edition of the same game.
We tried to credit you Battle.net Balance for the cost of your pre-purchase, but there was a problem trying to find the right amount of balance to credit. Contact us to resolve the problem.
