FNB Cash Deposit not reflecting

I did a cash deposit at an FNB ATM in Pretoria on 5 November 2022 at the FNB Branch at Olympus Pretoria . I deposited my notes into the ATM as instructed and as I always do and made sure that all the notes are in order and not folded so that I don't have to sit with the issue of the ATM rejecting any of my notes. The ATM took my notes and started counting them which took a while and eventually the ATM said that my transaction could not be processed and it showed that the ATM would be returning my notes and this too took ages to happen but never happened. In the end the ATM just gave me my card back and a slip saying that my transaction couldn't be processed and my notes stayed inside the ATM with nothing reflecting in my account. I told the security gaurd what happened and he said theres nothing he can do and told me to come back on Monday and that I must let the next customer use the ATM. On Sunday 6 November I went to my nearest branch (FNB Clearwater Mall) to lodge a complaint about the matter so that it could be sorted out and I was helped by someone who gave me a form to fill out and I was told it will be sorted out within 2-3 days. I've phoned the bank numerous times to see how far they are with the process and asked whats going on and no one can tell me whats happening all they can tell me is that I must go back to the branch where I lodged the complaint. I've been back to the branch where I lodged the complaint and all they can tell me is that I need to wait, they have "tried phoning the people on that side but no one is answering". I don't know what kind of a response that is, but its absolutely pathetic. How many more trips to the bank and phone calls do I need to make until I get my money?
