Poor student support service

I completed an online registration as a returning student and also attached a proof of payment. Its been over two weeks now, I am not registered, the first time I called I was told that my finances have not been cleared by the account department. For the past week I have been calling everyday without help. The person who is holding my account by the name Caressa doesn't pick up calls nor respond to my emails and therefore no one else can assist me because my account was assigned to her.

I have even called the Johannesburg office and they also refer me to the same person. I am frustrated by this as i'm supposed to be starting with my assignments. As it is, I don't know what to do anymore. I have even launched a complaint with the Student Support Service, but it looks like my complaint is not receiving attention
