On the 04/8/2021 @ 13:50 I was at African bank atm in west gate mall,deposited R2100.00 into atm,then the atm took 2000.00 and brought back 100.00,at the end of transaction I ddnt receive receipt nor a cellphone notification.then I deposited the 100.00 and i received the receipt. I then went inside the bank and asked for a manager,the manager was so rude,told me that I will have to wait for G4s to collect the money and I filled in some form.until today I havent received any feedback,when I call I'm told to wait and the manager is so rude
