I have dealt with a couple Admins and have reported a bug for the following, however, I feel as though my request is very simple and will not be dealt with by an Admin or through reporting a bug.
A few days ago I posted a Pearl of Power X to the Auction House, at approximately 2 AM. Later that day, at around 3 PM I checked the Auction House and was unable to find the Pearl in either the post tab or when searching for the item. I also checked my mailbox to be sure that it wasn't already sold, and it wasn't.
So, my simple request is a refund of my troubles.
