Absa cannot even assist when money was paid into a wrong account

we paid money on Monday 29 August into an fnb account, but unfortunately switched the last two digits around, we called absa 3 hours later to inform that to please try and reverse the money, before it can hit the FNB account no, I mean surely there is a way to do this as it was from Absa to FNB and the money should have taken a while to get to FNB, how do you not have such a functionality, we called again the next day to find out if Absa had been working on our issue, and were told they are, today is Friday 2 Sep, and we have had no feedback, we have been told that in instances like this, the bank is not able to assist, but this is rather dissapointing, surely you should be able to catch the money before it gets to the other account, and even if it does, that money does not belong to the other person, how is it ok for them to have the final say as to whether they want to give the money back or not, our bread for this month has been taken out of our mouths because we made a human mistake, and Absa whom we pay so much of fees to can do nothing
