I have been ignored several times while requesting for my refund of R3000

I had registered my Son at Spark Riversands for grade 1 2025.the registration process was finalised in august 2024.in December I requested and processed a cancellation for registration as i wanted to move my child elsewhere.I had called several times requesting a refund of the 1st month school fees of R3000 that I had already paid as per request.I understand that out of R3800 paid last year,the R800 might not be refunded as it was for registration.they have been ignoring my emails and follow ups ever since and I will not accept that I have just given my R3000 for nothing as its a lot of money and I want it back.I am very much dissapointed with Spark and their finance services.
