UNISA's incompetence

I have been struggling to complete my registration with UNISA since January 2020. The last time I registered with Unisa was in 2013 and my account was paid up. In Jan 2020 the system would not let me register because I apparently had outstanding fees (despite my account being paid in full). I eventually got through to someone who told me that I had an amount of R31 incurred due to bad debt for a library item. I HAD NEVER USED THE UNISA LIBRARY and was therefore perplexed at this fee. I subsequently paid the R31 so that my registration would go through. IT STILL DIDNT GO THROUGH. I lost a year of studies (2020) due to this.

It's 2021, I am still facing the same issue. "You have outstanding study fees on your student account. If you are a my.unisa user view your account on https://my.unisa.ac.za/portal (click on Financial Details)" My account is on R0.00 BUT I STILL CANNOT REGISTER ONLINE!

What needs to happen. I've sent countless emails to all relevant addresses and sms line, and yet all I received are automated responses and never ACTUAL assistance.
