Guild Wars 2

After I saved up a lot of Deadly Bloom tokens to buy some Nightmare Gear for my Necromancer, I went to Lion’s Arch to buy some of the gear. While attempting to click on the scroll bar so I could scroll through the armor to see which set I wanted (precision, toughness, condition or power, precision, condition), I’m not positive on what happened but I believe I clicked on an armor piece while clicking on the scroll bar and it bought the item. I never clicked “buy” for the item, it wasn’t even an item I could use or ever will use for any character, and now I cannot buy the armor I wanted to get. Either this is a bug or Guild Wars has something wrong with their merchants being scandalous where you can click to buy armor. In order to fix this problem, bug or not, I believe there should be a refund option on the armor you buy so you can get the tokens back and give back the armor piece.
