Been waiting for a Rosebank refund or at least communication for ages

I have submitted a cancellation form and all supporting documents to Rosebank in Polokwane from the start of last month and I am supposed to get refund after I had paid R28 100 around February. I was told I'll get 50% of the amount paid ,which made sense to me but ever since I haven't heard from anyone with regards to my refund, I went back to Polokwne campus to enquire and all I was told is that "it's been loades" , whatever that means. Then after I sent endless emails but I never got a reply. I tried the whatsapp number and I was told "we only deal with application" , I don't know if I am missing or what but according to my understanding, this shouldn't be taking such a long time since the amount paid does reflect on their system and I also provide proof of payment , and to make matters worse no one is telling me what is going on . I think college needs to work on their communication skill .
