Missing npc to turn in "The shadow rising" quest

I’ve had this issue for over 2 weeks now. Same quest, the NPC will not spawn after completing the requirements. It can not be turned in since the NPC is not there, and it is preventing me from progressing in the campaign on my first lvl 80 this xpac.
EDIT: It may or may not be helpful information, but the quest location can not be tracked on the map either. When it is selected for tracking, NOTHING appears on the map anywhere in any zone. No markers, no arrows, nothing. It’s like the quest doesn’t even know where the NPC should be, or maybe its location is tied to the NPC that isn’t spawning, so no NPC means no location maybe.

I could not post earlier, because there was a bug which was preventing me from selecting a character, which is required to post in the forums. Customer support would not help me with this quest bug since I hadn’t posted in the forums.

It is crazy to me that a bug that literally completely halts all progress on the new content has just been completely ignored like this. This really should have been patched within a week of being reported since it’s so majorly game breaking. Do they even have a team that fixes bugs anymore?
