They said they are not upper because they can be taken in your freshman/sophomore years of college. I tried to petition to get Theory III and IV accepted as upper levels. My professor for the Theory classes wrote a letter to TE explaining how the classes are upper division but I was not successful.
I know VCSU is accredited from the National Association of Schools of Music. It makes me think that if TE won't accept upper-level classes from VCSU they won't accept them from anyone else! I was close to graduating from TESC but now I am thinking I may have to switch. 
I'm bugged by your experience. Majors in the fine arts are different from other disciplines - you're expected to have an extensive background in the discipline at the time of admission. A very select few individuals can be successful in a music course intended for music majors without an extensive (5+ years) background in music.
I don't know if this is true of VCSU, but in most schools you don't get to take "music major" courses without an audition, exam and/or at the very least, an interview to determine whether you have a sufficient background in music. There is no survey course to serve as a foundation for all other courses in the major - you're expected to have that knowledge entering the program. A freshman that doesn't read music would get killed taking a 100-level professional music course.
The course numbering in schools with professional music degrees are more reflective of when you are expected to take a course rather than the actual course content. For example, some schools require the music history sequence at the 100-200 level, others at the 300-level and still others at a combination of lower and upper level courses. The actual course content isn't necessarily different across levels.
There are examples where music schools have obviously finessed course numbering or course sequences to comply with internal university-wide rules on the number of upper-level courses. I've seen the exact same courses (same textbook, identical syllabus) offered as 100-level courses and 400-level courses at different schools. Music Theory I is almost always a 100-level course at a school offering professional degrees in music (Bachelor of Music), but I've seen it at the 200 or 300 level in liberal arts schools with a traditional 30-hour BA major. Once again, same textbook and an identical syllabus.
In places that offer the Bachelor of Music (BM) it is not unusual for the Bachelor of Arts degree to appear "light" in upper-level content relative to other BA majors precisely because the course numbering reflects sequencing more than the level of content.
You may wish to get an evaluation from Excelsior or appeal further at TESC.
