I know this is not a correct format, but I could not find one for this particular subject. I was bidding on an enchanted book, and the auctioneer said "Aqua Infinity III" and I bought it at $600. He then gave me an Aqua Infinity I book. I requested a refund, but he teleported away and refused to refund me. I do not have any picture proof, but I am sure Chat Logs would show what happened. This happened around 4:50 PM EST on May 9th, 2013. The auctioneer's name is "LECKReilly". Again, I apologize for the incorrect format.
This goes in the Complaint Section found Here. The format is also there. But you will need proof for them to look into it
