ATM dispute investigation

On Thursday, 05 January 2023 at approximately 08:00am I had gone to withdraw money at the Capitec ATM in Promenade. After I had attempted the withdrawal of R2000 the machine told me I had exceeded my with withdrawal limit I then lowered the amount to a thousand and the machine still gave the same message and it told me to take out my card, a receipt and my card came out and I walked towards the main branch to get inside the bank for some assistance. While I walked I received a notification that an amount of R1000 has been withdrawn I immediately brought this information to the customer service agents at the branch they looked at the machine and put up a note that the machine is out of service. I was told that an investigation will be made, I went on and pulled up a statement while doing so I overheard the agents whispering in the Afrikaans language that a similar incident had happened the day before. My issue is that all these agents can testify that I had not received my money yet a notification that the money had left the account was there. I was informed that the investigation will take 24hrs however within 2 hours I received a message that the investigation had been declined. I'm highly disappointed in the Capitec Bank and their customer service. I would really appreciate if this would get looked at and resolved, if this is how Capitec is treating customers I would not recommend anyone to join this bank.
