UTA online bsn grade posting


I just started with taking some pre reqs. Spring 2016 was my first session. I had to take math 0311, a remedial math for TSI test. The class finished on 5/13 and registration for summer was 5/18. The computer system wouldn't let me register until this math grade posted. I started in calling and emailing several departments on 5/13 trying to get this hold off my account. I got the run around for several days and missed registration deadline for summer. Now it's 5/20, I'm officially screwed out of summer courses and they still haven't posted any of my grades for the 3 courses I took in spring. So I cannot take any courses until August. Has anyone else had this problem? If so, what did you do to resolve the issue?
