Unsatisfactory service/feedback for dispute locked with regards to a payment made from TymeBank account

Complaint with regards to the purchase of a pair of vellies from Veldskoen's website where the order failed and my son made an EFT payment from his TymeBank account to Paystack, a Nedbank account, on the 30/11/2021 for R1 119.The funds was taken out of his TymeBank to Paystack, but after putting in a dispute at TymeBank on the 9/12/2021,for which he was charged a fee of R160. Veldskoen never received this payment as the order failed via their website, therefore the funds was paid with an EFT payment to Paystack where this funds as in a Nedbank account. TymeBank send my son a sms with the response that they cannot reverse the funds, his dispute was unsuccessful. This response from TymeBank is unacceptable as the funds was transferred from his TymeBank to the Paystack Nedbank account and must still be in that Nedbank account. He would like to be refunded with his R1 119, as this is not his fault if the funds are still stuck in the system between the 2 parties applicable. This is not an amount that can be thrown in the water.
