Bug following Torghast questline

I finished the quest to save the Jaina “Torment Chamber: Jaina” and simply the Bolvar Fordragon does not make available the quest “Finding a Witness” I’m stuck in progress. I’ve sent more ticket they simply say they are “getting many tickets and can not help me” Concluding, we paid for them not to solve ANYTHING, I saw several forums with the same problems, the questline of torghast is completely full of bug. What’s to be done? Wait? For what? Blizzard every day disappoints us more. The expansion came out delayed and still full of bug. THANK YOU BLIZZARD :grinning:
