Unisa and it's DISGUSTING service

I am frustrated by how Unisa has been giving me the run around over a simple thing. Even when you call them...they take a good 10 or even more minutes to answer your call...just to refer you to another department....that won't even pick up your call. I made a minor mistake while applying online... I escalated the matter to the admissions department via email . Expecting them to attend my matter...instead they have not said anything. It's been close to a full month Now! I've got reference numbers that were sent to me. All I need is for the to rectify the mistake I made. I was then told to go online and create a "my life unisa" . Just to go visit either the Sunnyside/Florida branch to get assistance . And all my time is being wasted. The people at Unisa are pure lazy when it comes to assisting us... all that has to be done...is for this to be fixed. The same way I app**** online...is the same way I should be allowed to rectify my mistake ! I've been wasting my damn time not to mention my airtime ...just to fix all.of this & no one is taking me seriously. Can I just get assistance... you guys can't be giving us poor service when we need to be helped. It's plain wrong. I will NOT be mistreated over a mistake that I made & am trying to rectify.
