Refund issue at varsity college

I'm having an issue with Varsity College in Pretoria. I studied commercial law there in 2024, and my dad paid my tuition fees in full. Unfortunately, I failed all my modules, and the college owes me a refund for the prerequisite modules I didn't take. My mom and I visited the campus on the 3rd of March 2025, and we were told that only the payer (my dad) could claim the refund. After my mom contacted my dad, he spoke with Mrs. Chuene, and we were given a refund form to complete. We've emailed the form and supporting documents, but we haven't received the R12,000 refund yet. My dad has tried calling the college, but he's been put on hold, and we've had no communication from them. We're still waiting for our refund.
