The range hood we bought was supposed to be convertible, to blow air out either from the top or the back. When it got here it was set up to only blow air from the top, we need the back. The whole piece is riveted instead of screwed in, not at all like in the paperwork, so we do not see how we can change it easily.
First we tried to return it - they said it was custom (it isn't) and refused. We said fine, then please arrange the problem so we can use the hood (for which we paid 1000$+). At first they said they would, but now have said they have no one that can help and have washed their hands of us.
