Non payment of funds to inactive account

I deposited money via EFT from my capitec account into a FNB closed account on 24 January 2020. I phoned FNB to find out if there's anything they can do and I was told that the money will bounce back into my account. However, I still have not received the money into my account. I believe that the money did not bounce back into my account because there is not proof of that.
