No answer to emails or calls after several attempts and reference numbers. One star is still a lot for the ****py service recieved!Disgusted!

I have a refund due to me since August 2019. I have submitted the required documentation to "Finan" in December 2019 already and to date have had no response despite several attempts to follow up and three different reference numbers. Then one has been attempting to get through to UNISA for a number of days on the number they provide stating that all calls for student enquiries must go through this number (***) it rings for ages and when you eventually do get through the operator puts the phone down in your ear. How are we expected to follow up on our matters if you NEVER respond to emails or answer calls. You are unreachable. I was promised 15 days from date of submission of all the documents that I would receive my refund and almost a month later no response, feedback or refund. What kind of service delivery is this?!
