Bad Service/Don't Care about their students

Sent an email to Mancosa's accounts department and I was assisted by Aadil Pillay. He asked me to send him a motivation letter, which I did, no acknowledgement or response from his side. When he promised that I'll receive feedback by Monday the 3rd of Feb. Now another week is coming to an end still nothing. What is worse is that I've been asking him to call me as getting through to Mancosa during this time is a nightmare.
