I did call them the same evening, and I believe VA said you need Tk to deal with the new flights, so I didn't bother discussing this further. I just wanted to get home. Air Canda also said TK need to manage this, while TK just shrugged and said not our problem on the phone essentially.

Really solid and poor introduction to Australia by TK (Oh and the KL/Singapore stopovers are horrible).

So essentially everyone is doing the Spiderman meme

I've responded to their feedback again, and will escalate to ACCC or someone if I hear nothing else.
