FNB Not returning my money that got stuck in their FNB

I went to FNB Platinum Park in Polokwane on Monday to deposit my business money, I was not allowed to deposit inside the bank as they told me I can only deposit inside the bank when depositing R50 000 or more, which I understood. I then went to the ATM outside to deposit my money but the first transaction I did my money got stuck in the ATM. I then asked for assistance and was met with arrogance from the FNB employee accusing me of putting in more than 100 notes, which was not the case I always divide my deposits into less then 100 notes so the fault was on the side of the ATM.

I received a ticket for a call that was logged and I was promised I will receive my money back in 3 working days, it's been 5 work days so far and no response even wen emailing the support email they gave me. How do you expect people to choose FNB if this is how you treat your customers on the first sign of trouble ?

I need my money back so I can continue my business and so that I can close my account. No one can seem to assist me in receiving my money back, how does that work ?
