Not worth it, I would leave it alone and learn. I once bought the wrong necklace on my mage that I regularly played/raided with, it was with justice points or w/e.. took them two weeks before I got an answer, then the day I got an answer, a day later I was banned during a raid for association to exploitative accounts.. I was able to get it back since I was like wtf I was banned during a raid etc.. but they shouldnt have, since I was obviously associated to my farming accounts..
So you go ahead and try to get that money back, I wouldnt doubt you end up losing more than 87k
