It seems to be fairly rare for there to be a way to complain. They often make you log in to file a support ticket, but you can't log in anymore.

I suspect most of these companies have no real idea what their false positive rate is.

And even if there is a way to complain, unless they take action to reverse the decision it's probably not considered a false positive. And most complaints probably achieve nothing.
