Intec college is the worst

I have been studying with them for 6 years and I still haven’t received my national diploma certificate in educare. Their head office is based in Cape Town so I have been communicating with them via emails Now they have recently stopped replying to me and it’s so frustrating because I have paid already for my certificate and I have submitted my documents. No one seems to help me with this situation. Ingrid and sumaya who was supposed to help me have stopped replying to my emails I’m so fed up of this ********* college There is no else who can help me I email them every single day
