This number belongs to Collegiate Admissions and Retention, a third party college admissions marketer in Birmingham, Alabama.  They use it to call prospective students who've expressed interest in attending the school.  If you are really interested in going, the school can be reached directly at 864-250-8000.  You should call both numbers, the first to ask to be removed from their call list, and the second to complain to the school about their abusive marketing practices.
