I would call and keep trying at various times until you get through to someone. Unlike some other schools that are strictly a medical school, NSU has numerous professional schools that fall under the Health Professions Division (HPD) so things can get hectic in admissions. Good luck.
I would advise everyone, especially people who have already interviewed, to stay in touch with the schools that they are interested in and make sure that their file is complete (even if they think it is) so that they can be reviewed. Taking a more active role in the process can really make things run more smoothly and more quickly.
The medical school prefers not to be called Nova because the medical school used to be Southeastern University but merged with Nova University in 1994 - making Nova Southeastern University. Because of this, they prefer to go by NSUCOM so that the merger and both entities are recognized.
