Professor that refuses to teach?

You can't get a professor fired. The most you can do is complain to the department head, but the most they can do is make someone else teach the cl next time. And you should complain, but the most that will happen to the professor is that they don't have to teach anymore, so they win. If he teaches many cles or other students in the program have experienced that with other professors, it might be a good idea to transfer to a different school.
