Hallows End bugged as I cant get into Undercity

Got as far as I can trying to figure what to do. Its seems that everytime i go to Undercity it kills me. I went onto the in game support and they said that I need to pick up the quest “Call to Loraeron” from the Forsaken Dreadmage. When I went to Oribos the Forsaken Dreadmage has no quests for me. I am not sure what to do.

I cannot even participate in the Hallow End event and I cant get help from blizzard anymore with the way they changed their support ticketing system. I am at a loss. Anyone have any ideas of what to do?
