Cancelled class

Today I got notified of one of my core classes (cs) getting cancelled because there werent enough people who enrolled. I checked that class and saw there were two sections of the same class which didnt have enough students so i emailed the chair of computer science saying they should just combine those two classes which would result in keeping one class instead of cancelling both and risking students’ enrollment in that class. The chair did respond with an email but ignored the main issue of cancelling the two classes and just nitpicked me about the number of students needed to cancel a class. I checked recently and they really did just cancel both classes putting ~20 students out of that core class. Most of those classes are already full which totally just fucks me over and im sure many other students. I already feel behind on my pathway and not being able to take this class already puts a sour taste in my mouth before the school year even starts. Im looking to enroll in that same class at a cc but atp i shouldve just went to a cc instead of this school. I just feel like i cant rely on the institution at all as a computer science student and regret coming here instead of a UC/CC
