Standard Bank Instant money

Hello Peter, My name is Tebogo , I had a bad experience with Standard Bank Instant Money, I made a transfer on the 28th March 2019 for R1000.00. I then send the number to the person I wanted to send to but when they trie d to withdraw the money the ATM machine said the voucher number has been used. I then made a call to Standard bank instant call center Ref: ********** I was promised to get a response with an SMS in 24-48 hours but that did not happen I called them after 3 days they told the money was withdrawn. Then they said if I'm not satisfied I can phone the number ********** 1011 I spoke to Levi,she said they will investigate, then send me an SMS ,nothing was send to me then I called them after some few days,they said to me sorry the money was withdrawn and they cannot refund me. But no money was withdrawn all I ask is that investigations must be properly done as I believe there are CCTV on the ATM then it must checked and they must give me back my money .I work had for that money and if the ATM machine was being fiddled with then someone must take responsibility . Please assist Hello Peter I desperately need my money back Regards Tebogo
