Hello,
abandoned the quest, and upon taking it up again the NPC will not provide one of the 2 required quest items (Ensorcelled Choker). Even thought the NPC has a dialogue option to ask for a new one, when I press it nothing happens. Not even after relogging/restarting/turning off all addons.
Submitted a ticket but the timer says the wait time is 36+ days… 
Any tips maybe? (Regarding the original issue and not the response time. :P)
Edit: I’ve found the solution but will leave this here if anyone needs the info… So, you can ask for the Choker even if you dont have the quest. This way you get it, and THEN retake the quest.
Cheers
