Poor service

I did a transfer on the 02 April 2024 to a Bidvest bank account however the account number was incorrect. Immediately after I saw that the payment was done incorrectly (which was on the same day) I called Capitec to assist with the reversal on the funds, mind you I did a normal payment not an immediate payment, I was told that I couldn't be assisted and I need to go to the branch, this was past 6pm. Long story short, I went to the branch and the consultant assisted me since it was not an immediate payment, before the turn around time, I was told my request has been denied because the funds were not placed on any hold and had been utilized. How is that possible when I reported the matter immediately to my bank before 24hours? I'm not happy with this outcome and I'm considering changing banks. I need this matter attended to asap
