Poor Customer Service from Mancosa staff

I am not happy with the service I have received from Mancosa and to be specific student advisor Dacian Kadavelu. I have been communicating with Dacian Kadavelu from the 05 February with regard to my Adviced Diploma application. I have sent numerous mails and try to call him after he agreed that he will assist me with no luck. I have explained to him that the funding for this qualification is from my company meaning I need to submit all relevant documents by the end of business day today as the closing date to apply for a bursary is 07/02/2025.

I have submitted all the documents that was need from my site and sent him many emails and called him but he didn't respond until i sent another email cc(copied student services on the mail) he then responded immediately that he is busy with my application. He called me around 3 saying I need to change my course and which I did but he never reverted back to me until now.

I am not loosing this opportunity because of *********** staff which are not doing what is expected from them. I have proofs of my emails and calls which proves that he assured me that by the end of today I will have pro-invoice acceptance letter which Istill haven't received until now.
