Accidental token purchase need advice

Hello, I have a question regarding a token I exchanged by mistake. I was trying to buy gear for my main specialization, but I accidentally selected the item for another spec. Immediately after, I enchanted the item (out of habit), not realizing it would make the situation worse. I know it was my fault, but I would really appreciate it if there is any way to undo the purchase and recover the token. I am happy to provide any additional information or screenshots.
Character: Hextech
Server: Onyxia
Token type: Mantle of the Lost Conqueror
Item mistakenly bought: Valorous Shoulderpads of Faith
Enchant used: Greater Inscription of the Storm

I tried to create a ticket, but the only category available is "Ban Appeal". There is no "Item Misbuy" option.
Should I create the ticket under "Ban Appeal" anyway and explain my issue there, or is there another way to submit this type of request?

You have to get a new token. There's a reason for those "are you sure?" pop-ups to exist.
