Appeal for Late SIR

I accidentally enrolled in UCI because I had an enrollment fee waiver, but I was already enrolled in another college… I didn’t want to get in trouble for that so I unenrolled from UCI. I realized I made a big mistake with the enrollment with my original school, so I ended up appealing to try to reverse my decision for UCI (explaining my circumstances with financial reasons, etc). What is the probability they’d let me re-enroll or did I totally screw up everything?
