UNISA Tole-free Call Centre Without Answer

My wife app**** for their teachers short learning program last year the day admissions opened. Documents submitted and fee paid, yet we haven't heard anything back. When we select to track her application status the website says she must apply for a formal student number... Then their tole-free puts you on hold indefinitely, right now I have been on hold for 2:30hrs and I have been calling when and where I can this past week...
