Except Blizzard has excellent customer service, with representatives that actually communicate with the players. Bioware's CSRs just delete our in game tickets or reply with a copy + paste response saying to wait until the next patch.
Again, you missed the point. The OP is not complaining about having to wait, he/she is complaining about getting a piece of mail saying that his/her item sold.
In beta I bought gear with Warzone Commendations in the Kaas City cantina around level 15. Now there's no PvP gear vendors there but now near my class trainer. However he only sells level 50 gear. Is there no longer PvP gear to buy before level 50 or is that vendor somewhere else?
