Poor registration

I am extremely disappointed in Mancosa. I paid them the full amount for my MBA at the beginning of the year. I discovered that I was not registered for all the modules I was supposed to. For over 2 months, been calling and emailing them and been sent from pillar to post to rectify the matter. Its August and I am still not registered although I passed all my modules in the 1st semester. I was assisted by Yonela to register, but has been avoiding my calls and not responding to my emails.
