Sorry you are having trouble with what should be a simple task.

It fixed itself suddenly
After logging in and out a few times the purchase finally went through
Thanks though! Should i still submit a question or something? So they are at least aware of a glitch like that?
Glad it got resolved!
(I meant to suggest logging out/in a few times, but based on your original post, I assumed (incorrectly) that you had been dealing with this for a few days and had already done so. My apologies for delaying the solution for you.)
When in doubt, I believe it’s worth filing a /bug (in-game) or a ticket (via the website) — it’s up to ANet to take our reports and decide how much importance to give to them; if we don’t tell them about our annoyances, there’s no chance those will get fixed.
But in this case, I believe ANet is aware of the issue and would have resolved it already if it was merely difficult to do so. It happens from time to time that people buy gems and the game doesn’t “notice” until the player logs out and the gem interface has a chance to update.
