Faulty ATM, stuck, money not dispensed R1000

On Friday at 15:05 in the afternoon I went to Soweto Meadowlands zone 2 at Meadowpoint Standard Bank ATM to withdraw R1000 that was sent through pep. I put in the voucher number and Pin, the ATM started making noise like it's dispensing money but nothing came out the screen was stuck on "processing transaction" I called securities and advised them what was happening, I told them I won't move from the ATM until I get my money. I tried touching the screen to cancel but the screen was not responding after a few minutes it displayed limited service. Cash and instant money not available. I left to go to pep and ndofaya mall where they told me that the voucher reads as inactive, I went outside at another STD bank ATM and this time it said voucher already used. Standard bank please investigate and provide footage as well because I did not receive my money. Your ATM was definitely faulty. This is urgent because it money for my son's school fees.
