Standard Bank ATM Deposit Failure!!

Today at about 16:58 I was making a deposit at an ATM Standard Bank at Bayside Mall, Cape Town. I put in the account number as well as the rest of the details required and inserted the total amount of R5000 in notes, the machine calculated and returned some of the notes (totalling R1500). The machine then prints out an error slip, stating there’s a technical error and to try again later and does not return my R3500 nor does it process it to the person I was making a deposit to. I stood at the ATM and called Standard Bank and was on the phone for an approximately an hour to try and have the issue resolved only to be told that an investigation will be done and I must call back again on the 28 Feb 2024 with no assurance that I will get my money back! What an inconvenience! This ATM needs to be shut down from this mall! This is a second incident in less than a month!
