Frozen companions during combat

Is it possible to request a refund or partial refund of the game?

This bug is basically making the game unplayable for me at the moment. I love using tactical mode to fine tune my strategies and take on extremely difficult encounters by micromanaging my team. I die a few times, learn from mistakes, repeat...etc. I'm currently fighting one of the dragons and executing a pretty good game plan. I usually get the dragon down to about 30% health then suddenly one of my members freeze up. The workaround (exit tac mode and jump) is NOT a solution since the 2 seconds where my team is un-managed is all it takes for everything to go south. And I usually only notice the bug when someone doesn't move out of dragon fire after I instructed them to do so, so by the time I take manual control and jump it's usually too late.

I just wasted about 2 hours trying to kill this dragon, each failed attempt a result of this bug that got INTRODUCED in one of the previous patches? As much as I enjoy this game, I currently don't have the will to continue playing since every difficult encounter from now on will probably be like this. 

Have they said they're not going to do any more patches? I knew no more DLC, but they did patches for DAII for a LONG time after it was out and all the DLC was out. I can't see them not fixing bugs like this. 

I'm just glad I'm not alone with this bug. As long as it's a known issue, I'm going to mark this as solved, but I'd really like to know if they've said they're not going to do any more patches. There are a few bugs yet with this last one including this, Triffles Minutiae in the dungeon at Skyhold, operations not showing up at the war table, the Divine bug (Wrong Divine given your choices during speeches and such), etc. They have some stuff they can still fix.
