Terrible service

I have had endless problems with MANCOSA. now that I have finished my exams and my degree, I have not been given a correct invoice, which I know I have paid all fees up to date. no one within mancosa can tell me what the invoices are for or why it has not ben rectified. I am meant to graduate this year and I don't have a graduation date or venue. I will never recommend Mancosa to anyone. worst service and treatment ever.
