Failed ATM deposit - No feedback from FNB

On the 10th Aug 2022 I reported a failed ATM deposit - reference # ***. Sent completed form and ATM slip as per instruction I was given when I called to report the incident. I was sent an auto reply email saying I will get a response within 5 working days. I waited for 5 working days but no response and money was not deposited into the account, I sent a follow up email on the 18th August 2022 - NO FEEDBACK STILL.

How long does it take for the branch to calculate the money deposited into their ATMs and for them to check their CCTV footages? I'm not happy at all with the service.
