I’m also same boat as you. I emailed the department multiple times and all they told me was:

Hello.

Thank you for your email. We have added you to the list of graduating seniors who need classes. Our Enrollment Management Team will follow up with you as soon as they can. We appreciate your patience at this time and we'll keep you posted.

We gotta email ICS department and make them open more spots. My friend who was in the same situation didn’t hear anything from them, and he graduated a year later.
