Poor Poor Poor Management and Service

I've been struggling to register for my postgrads since January till today, Makwena and Abigail have been reaching to them regarding the application with useless help sometimes they don't respond at all, i got proof sometimes they do for the very same error or issue i am experiencing, i currently a Mentor and i am suppose to be tell Mentees what lies that this works for me, whereas the service is horrible, - this is heartening to say the least, what do i do from here?
