A weird situation I'm in

Ight boys, so prepare to get mad about me paying $30 to swap factions instead of just starting another Demon hunter. So I started a demon hunter, everything is good, everything is fine. I realized that I accidentally made it alliance, I got up to the first quest in stormwind, detected the demons. Then did a couple battlegrounds since I have a couple of friends on Alliance anyway that were on at the time. After that, I gave Blizz my $30, and faction transferred. Only problem is that when I faction transferred, I am no unable to start the legion quest to gain my artifact weapon. With this problem, I can’t really do anything except battlegrounds on my 102 Demon Hunter. Any ideas on how to gain the quest?
I have tried?: Hero Quest board in Org, Talking to Holgar Stormaxe outside of Orgimmar. I have no way to get to Broken Isles Dalaran due to portals not working.

What should I try next? I have already submitted a ticket since I really can’t think of any ways to fix this character.
