Rude and unprofessional staff at NMMU Contact Centre

I made a call to NMMU today. The contact center staff was utterly *********** and rude. After the 4 the call because 2 calls cancelled while I was hold and the 3rd was transferred to the wrong department the rude operator dropped the phone because I refused to take the number she wanted to give op of the department that I wanted to be connected to since I told her that I have the number already. This behavior is disgraceful. NMMU should employ competent staff and train them regularly to deal with customers.
