Mancosa online marking system is terrible

I am studying with MANCOSA and I am very frustrated with there online marking system. I submitted 2 assessment and after a month they showed I had failed because I did not submit the project. So I contacted them and they said it was glitch and soon as the Mark's are out it will automatically update. Well the Mark's are out and only one updated and the other still says failed, even though my assessment has been market. Last weekend I submit another assignment and now it says that I have failed and must re-register. This is highly unprofessional from an institution that is meant to be offering international standard education. My company is paying for my studies and with this sort of service I'm considering doing my next year else where and I will inform the company to change service providers for over 20 people that are studying through mancosa to some place more professional.
