Unredeemed instant cash voucher

I have a savings account with standard bank, on Thursday 28.08.2025 i visited the Kempton park ATM by the taxi rank to withdraw cash, but because I was at a high risk area, I decided not to use my debit card, but to send myself an instant cash voucher. I did that while I was standing in front of the machine, I got the voucher number and within seconds of receiving it, i logged it onto the machine, I got a message saying "SORRY THIS VOUCHER HAS BEEN REDEEMED" with worry i tried again for the second time and the same message came, and I tried for the third time and the same message. Because I was in desperation and needed cash, I then used my debit card to make a withdrawal. Then I drove back to my arear and went to the Lake Side branch, tried again the voucher number at the ATM and it said the same thing, I went inside the branch and they asked me to call *** where I was given a reference number to follow up after 4 days, I do that and the resolution is that i got the money. Tell me where is the logic of me trying 4 times yet I got my money on the second attempt as the agent says, where is the logic on me sending myself cash, i get it then withdraw cash again from the same account. Nonsense. I need proof that i got that money, i need evidence of seconds and minutes proving that i got this money. I need footage showing that i received the voucher money, not footage of my cash withdrawal. I am very upset, and I need my money back.
