Unreverse payment

I transferred money to an incorrect account number on the 7th of this month and today I spoke to the person who was supposed to receive the payment and she confirmed that she didn't receive the payment, I then transferred the money again thinking it was an error from my side only to realize that the account number is not valid, I then went to the branch in Braamfontein trying to resolve the matter and it was completely waste of time for the tellers being casual about the matter not showing compassion or interest telling me it can't be reversed or I have to call some, number, like what the hell is this last time I lost my card and someone made shopping using my card to pay, tapping and I was told the same thing, an amount close to 500r was gone just like, why can't we reverse the money like any bank
