Worse customer service ever

I was trying to apply for my son for late application for academic year 2021,I am shocked of the service are I received.I have been calling them since the the 1st of March 2021 till today,I even send emails but still no one is willing to assist and they all pass me from one person to the other and Vanessa even told me that I can't complain there is nothing that I can do atleast Veli tried to give me by providing alternative numbers to call.The application is pending n there is a restriction which I don't know what it means and all I wanted was for some to assist me were I made the mistake to fix as Nsfas is waiting for university registration and a way forward,I even got direct email address for the people working in admission which were Faith,Sylvia,Mosele,Motsamai and Relebogile and none of them rep****.I have never been so frustrated like this before were I feel helpless and so now the registrations are closing on the 12th,I guess I am not important as I never went to university and now my son won't get the opportunity that he worked hard for under the covid circumstances which he passed with a bachelor's and I am so sad and heart broken .I even paid the registration fee even thou I don't know the way forward and I even got the banking details on the website as I have been requesting them since last week
