MANCOSA- ******* ADMINISTRATION

I am suppose to be registered to complete my second year in BCom Supply Chain Management but unfortunately I can not because mancosa is messing around with me since last year July. They haven't yet graded my End-user Computing Assignment 3 from first semester July 2019 and I am currently still waiting for a response from student services and when I contact mancosa I have to wait over 20 minutes for someone to answer and when they do answer and put me through to student services they then always cut my call and I have to call again and wait for another 20 minutes or sometimes even half an hour for a switchboard operator to take my call and this is ******* service. I have paid in full and I have sent proof of full payment numerous times yet they have not responded to my previous emails or calls. I have been trying to deal with this situation from July 2019 and we are currently at the end of January 2020 and nothing has been done, when I call and finally speak to a consultant they never help or assist me, when I ask to speak to a supervisor they cut the call on me and they keep giving me references and different student consultants but not a single person has helped me or contacted me back regarding my situation. I'm a very upset and I can't complete my registration for 2020 because this is holding up the process. I will probably end up failing my first year because of this terrible service they offer and they are quick to take your money but slow to grade your assignments. I have been through almost 9 consultants and not one has helped me or responded back to my emails. I have about 6 ticket numbers and not one has been responded too.
