CONSERVATION FEE REFUND - DID NOT ENTER THE KRUGER NATIONAL PARK

We mistakenly thought we had to enter Kruger gate on 31 May, but we had a reservation at Lion Sands. As we mentioned to the staff at the gate they took payment of conservation fees, 2 adults and 2 kids for 2 days. Where after they also realized we do not even enter the Kruger National Park at all. I requested a refund right there and then. The staff member scrambled around not knowing what to do and how to manage a refund. After a call to a colleague the transaction was voided on the reservation system. I asked, what about the R280.00? The staff member, fully believing he's making sense, the money will just "bounce" back to your account?????????????? Asking but HOW? As you do not have my banking details? Nor does the credit card machine???????? Confusion among the staff. So I just told my husband we will take it up with Sanparks reservations after the weekend. Surprise! After numerous e-mails and phone calls. Still nothing, today marks a month after my initial e-mail. So how do you go about getting a Conservation fee refund from SANPARKS?
