I have had a ticket in for 15 hours, and have watched the “average wait time” tick up to 36 hours now. Every hour that passed today, just added an hour to the wait. Does Blizz not respond to tickets on the weekend? I thought it was 24/7/365, seems like my issue would be an easy fix.

Well, as fate would have it, I just received a response. They did mark the quest complete, and said it was a known bug.
