Pep and Standard Bank Instant Money Voucher *****

I recieved an Instant Money Voucher of R1000 from my nephew on the 02 June 2022 at16:42, I went to Pep at Brixton to draw the sent funds at 17:20:55 with Transaction *** and the consultant whom is a gentleman whom was wearing glasses said that Standard Bank Money sends are a problem ABSA is better he asked for my ID again, scanned it and attempted the transaction as previous and it came back again with a slio printed voided and that was at 17:21:53 he then said 'hai broer try Pick n Pay which was in the same Brixton Mall, I went to Pick n Pay and gave the lady the Reference number she asked me to enter the supp**** pin and it immediately said the voucher was ALREADY REDEEMED on her screen, she asked me to repeat the Reference number and enter the pin and again it said it was redeemed I told her I tried withdrawing from Pep so I went back there and requested the receipts they refused to give me hard copies as they saidbit was for auditing and they said I must take photos, I did so and another eldler gentleman (assuming is the manager) in glasses gave me a number *** as I was leaving to follow up what happened I called the number it advised me about operating hours and calling tomorrow, I went tona standard bank ATM in Newtown after speaking to my nephew about what happened and attempted to withdraw the money and it gave me an error saying the voucher number for the payment has already been used, please advise what is happening as I did not recieve the money, I am very disappointed and stranded due to such poor service
