Unsuccessful Recall

I made a deposit from my Nedbank credit card to my husbands FNB credit card. I incorrectly added the credit card account number and made the payment on the 22nd of April 2021. When we realized that the funds were not received i requested a Recall application form from the consultant that assisted me on the phone on the 29th of April 2021 and sent it though. I received no feedback after 7 days i sent a recall enquiry to which i was told that the recall was not on the system as the consultant that sent it didn't send one with a reference nr. When i forwarded it to the enquiry email i was told that it is unsuccessful due to them not being able to recall from private debit/credit cards. I phoned again and was sent to missing payments with the ref ***. Until now there has been no further feedback except that the funds are not with Nedbank. I logged a complaint on the 13th of may with ref ***1 and the matter was since then escalated. When I did a follow up I was told to contact FNB in my own capacity. FNB could only confirm that the account exist and Nedbank has to send a request to them and not me. I filled a second Recall form as advised by a consultant at the branch which was again unsuccessful, to which I called the cards division and put them on call with FNB. My banker at FNB gave me a number to give Nedbank to phone and request a recall . R19000 is a large sum for such treatment. FNB has a procedure for the same incident but bot Nedbank....when and how will I get my money back? I asked for the banks POP and the system was down. What is the correct procedure to follow in order to get back my money before 30days lapses?
