[ANSWERED]Can I get 25 marks back for my Wintergrasp backpiece?

Hi, I am wondering if it's possible that I trade my 'Titan-Forged Cloak of the Victory' back for 25 Wintergrasp marks? My wife ended up accidentally buying this piece and without realizing it, I had come back online a few hours later, played for a bit and now I am not able to trade the piece back to the vendor for the marks, as the 2 hour duration had passed. I got this back piece a few days ago on accidental, so, hopefully this can be restored?

I am currently playing on the Icecrown server, Alliance side.

Thank you for reading this.

Most likely not, but confirm with Game Masters by making an in-game ticket.
