Send iMali Mistake

I accidentally sent money via Nedbank send iMali to the wrong person, since I was using a phone and not a PC I pressed on an 8 instead of a 9. I immediately tried to reverse the funds and when I realized that I couldn't, I called the bank. I was told there was nothing the bank could do and I should wait 48 hours for the money to reverse into my account. The money was sent to this person with a pin and the person could easily go to an ATM and withdraw the funds. I asked the agent that I was speaking to to get me the manager. The manager by the name of Busisiwe told me the exact same thing and that all they could do was "track" the funds to see if they were withdrawn or not. How will that help? She then told me that they would call me the next day to inform me of the progress of these funds. I never received this call, I called the bank myself and I have to call them again today to check on the funds. I was previously using Standard bank and their version of this function is called Instant Money and it gives an option to reverse should you make a mistake. Nedbank has disappointed me a great deal, even the attitude towards this situation has been terrible. It was not the first time I was disappointed by them. As soon as I get the time I will be changing banks.
