Refund from UJ

Good Morning I have experience a bad service from the UNIVERSITY OF JOHANNESBURG(UJ) I paid registration fee for my nephew which amounted to R5000.00. They then told me there's no space anymore after payments and promised to refund me back. It's been 5 months now with no respond from them. I have been sending endless emails with payment receipt. I made the payment 2th February 2024. I will really like you to intervene. Thank you.
