VERY BAD SERVICE, INCOMPETENCY AT IT'S BEST!!!

I still have a query that remains unresolved. This matter has been going on since the 05th of October 2019, it is 1 year old and 3 months now. I had initially requested an extension for an assignment, it was granted. I then had my assignment done and submitted earlier than the due date, it was the 05th of October 2019. Unfortunately, Mancosa had IT issues on the day. I then sent screenshots showing the error and my completed assignment to student services. THIS PRACTICE WAS PREVIOUSLY DONE - REFER TO TICKET NO: 291637 (Assignment submitted in this manner, in May 2019 was accepted but when done again in Oct 2019, it is unacceptable). After this submission, i was under the impression that everything is good, until i viewed my results and they stated that I failed the module. I queried this issue but I was sent from pillar to post, no one seemed to understand and wanted to help me resolve this issue. I was then told to re-register for this particular module and re do it again - this means paying for the fees in full. I decided that i will not do so, as I had completed all my assignments on time, it was Mancosa that had IT problems when i was ready to submit. The proof that shows that i have been sent from pillar to post is all on ticket number #343599 Business Management 1B and they keep closing the ticket though the issue is not resolved. Now i can't receive my results for the previous year, 2020 as they say i owe fees, for this particular module. This is a huge set back, in this Lockdown and Corona era, to repay for something i am not wrong for. Mancosa lacks investigating skills and resolving student issues in time.
