Apologies if this has been asked before.

I recently submitted 2 queries/reports to Ancestry, as when I clicked to view the Census returns in question, the images presented to me were completely wrong.
I just wondered, as a general point, are Ancestry good at correcting these reported errors?
Will they just correct them, and not tell me that has been done?
Will they correct them promptly... or take ages?
Or will my reports just go into a black hole somewhere?
I guess I want to manage my expectations!
