Were they something sent before the WotLK launch? I’ve seen other errors similarly, due to the fact that those items weren’t supposed to be available as yet and they were supposed to have been removed. Because they hadn’t been they were borking folks out.
Now, if that ISN’T the case, then Darth is correct. You just need to post in the master thread and they’ll get you taken care of in the morning when the staff gets back in.
