Argent Champion No longer available in SL?

I cant get the Argent Champion title now SL is out? I was part way through it. Like I had done Stormwind, Ironforge and Darnassus, was 5/25 through Gnomergan. Totally turned me off the game. Also, I can’t even raise a ticket in game.

Update 12 Jan 2021
Just to update this in case anyone ever reads it. I did the quest after the pre-patch whatever expansion intro finished. Icecrown went back to pre-SL and you can still get the Argent Squire.
