No answer at 12:30 pm??

I have been registered for 2015 and have paid my fees but the semester that I am registered for is incorrect.<br> <br> I have been trying to call Unisa to fix the problem but nobody has answered the phone.<br> <br> I have called between 12:30-13:00 and 3:30-4:00 and not one person has answered the phone.<br> <br> I take my studies seriously and I question if they do as well.
