Guild Wars 2

Hello, I was buying packs of 5 keys by clicking via “Recent Purchases” and accidentally re-purchased the Bouquet I already purchased Yesterday. I have mine in the bank and have no use for a second. I was hoping this bouquet could be taken back for my 400 gems in return? I haven’t accepted the bouquet from the mail yet and am enclosing a screenshot showing the mail and you can also see in recent purchases how it was purchased twice.

What happened was the Bouquet was the last purchase so it was at the top of my “Recent Purchases” and when I started clicking on the keys in that list to buy more, the list moved down and I clicked the bouquet instead of (what I though) keys.
