I bought gems to buy it and its gone…
Due to an error, those items inadvertently became available for a short amount of time. The items are not quite ready yet (there are bugs). Their appearance was just a listing error that we corrected immediately. We are still working on them. You can expect to see these items in an upcoming game update. If you purchased them, you will be refunded and should go through Customer Support for that. Thank you.
If you bought a Makeover kit or Hair kit within the last 2 hours and haven’t received it, please be patient. We are working to resolve issues with the Gem Store.
However, if you bought one of these items back when this was originally posted, and were charged gems but did not receive an item, please file a support ticket at support.guildwars2.com
