Pathetic Service/Arrangement Denied/Learner misses online classes

I would like to express great disappointment and regret to have registered my sister at Rosebank college. I got a very disturbing call from Dineo from Rosebank college accounts department regarding my sister fees as i behind with payment. Her number is ‭***‬. I called and was very rude towards me telling me that my sister is blocked from attending online classes. Exams and tests etc i told her that i want to make an arrangement to pay as i have lost my income because of Covid. She said its not her fault covid happed and its either i want to make an arrangement or not. She was quite disrespectful as i told her that ive paid a total of 12 thousand thus far and i would like my sister to continue her classes and i will pay monthly 3500. She refused and said the day i pay the 3500 next month she will unblock her? Is this ethically right? Everyone suffered because of this Pandemic, does the department of education know that students didn’t set foot in classes for 6 months or so yet we expected to pay fees despite us loosing our livelihood? Dineo didn’t appear to care i would like to officially right a complain to the head office Rose bank and department of higher education for this. Its totally unfair that i want to make an arrangement its denied. The student is missing her classes and at the end of the day she will be expected to pay in full for classes she was blocked out for?

Can these questions be answered please

1. Why do u give people who are very disrespectful to call parents and threaten them regarding payment of feese

2. You guys say we signed a contract. We did yes but that was before my income was affected by the covid pandemic

3. Is it fair to exclude someone from classes? Ib the contract that was signed theres was no mention that the student will be expected to attend 100 % of her classes online etc but yet if fees are behind they are excluded from those very same classes

4. Lastly why Did Dineo from accounts department refuse the student to be unblocked? Were will she get the content of those lectures? After the account is paid will she be compensated for missed tutorials exams tests etc

This is quite disturbing and id like to officially wrote a complain about this Her student number is ***2. T. kokome

Please do get back to me with regard to this
