I just got disconnected from battle.net during an arena game, and when I reconnected, I had been given a loss (lame) AND my wins had been reset from 3 to 0, wiping out all of my victories. Since this was my third loss, I'm now staring at a 0 win key and a complete waste of my 150 gold. Please help!

Edit: I chatted with a GM online and he says that Arena is a fully automated process and nothing can be done. He's going to pass the bug report along to the community team, but is not aware of any fix for this bug.

The bottom line here is buyer beware. I suggest not spending any real money on the arena until it's fixed and you can play with confidence that you will be able to keep the rewards which you earn.
