missing 1099 from defunct exchange. I've been dealing with this for about 5 months now and the situation isn't improving.

Look (at least in my experience), my buddy went through something identical.

What trips people up most is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.
