My bank call center did not help me.

Yesterday I got ****med by someone saying that he works at auction nation SA. I made a payment via bank money App which was not an immediate payment at 13:15, then at 17:37 I changed my mind and called the call center *** to reverse the payment the call was answered by Mabuela M (Mmabo) when I asked her to stop and reverse the payment she said she will send me a form of recall, I asked why she cannot reverse the money hance this has been done before she did not answer me, the form she sent me did not open both on my phone and on the computer. Upon releasing that the form does not open I called the center again at 18:01 Dlamini N (Ntuthuko) answered he also send me a reversal form which did not open as well. I have been failed by my bank call center why have a call center which has agent that can not help in times of need my payment was not a immediate payment has it have been stopped within the time I changed my mind of 5 hours after the payment my money would have been saved and I could not have been ****med. My right of changing my mind have been violated and the customer is always right was not right to the bank call center agent.
