Missing Payment from FNB to FNB account

We transferred significant amount via online banking from my living partner FNB account to my FNB account, but the payment did not reflect on recipients account. Called FNB and were told that it takes up to 24 hours to clear and there is no one to attend and resolve the issue. We find this totally unacceptable. To clear a payment from one bank to another takes 1 hour when using pay and clear option. Spoke with Sophy Maeuye, who asked for full authentication of my partner, from whose account payment was done. Then said it takes up to 24 hours. Went to Northgate FNB branch where accounts are and told there is nothing they can do. Very disappointing.
