If you wish to indicate a mistake in interpretation, choose misinterpret or misconceive. For casual situations where someone simply cannot figure something out, not get it or be confused works best. Always ensure the opposite word creates a clear contrast with the original meaning of understand without sounding forced or unnatural.
