Allocate the money or refund money back to cheque account.

I made a transfer from cheque account to FNB credit card account however the money never reflected on the credit card. Seven days later I contacted them was told to wait for 15 days for a refund to occur or allocate funds as per my request but that has never happened up to today. It was 25 April 2022. It's almost a year now. So upon doing follow up was informed that refund did take place categorised as payment made in error but it doesn't show who got the refund or to which account where the funds were allocated to. Please assist. Reference number:Kean11H46am
