Unisa owes me R12K and I am broke and hungry

This is my second time on Hellopeter and I am being ignored.Unisa owe me R12760.00 it's a lot of money for someone that is no longer employed. January 2022 on the 27th I canceled my wife's modules because I was no longer employed and I requested for my refund as I was still qualifying for my refund. I only received an automated email that they have received my email and I will get assisted within 24 hours and today is the 8th of may almost 4 freaking Months.. I don't know how i can escalate this matter further because I see they don't bother checking on Hellopeter, I also wanted to apply to study at Unisa I guess I will take a pass....They are inconsiderable.... I am tired
