Nedbank not responding to FNB atm dispute after more than 10 days.

I tried to withdraw R3000 from a nedbank ATM on the 28th of April 2021 just after 6 in the morning using my FNB Business account card. The atm gave me my card back but then stalled for a while and gave me a message saying the transaction cannot be completed. It also did not give me a receipt. The money however has been deducted from my account. I called fnb and they gave me a form to fill out and after a week of not hearing anything i went into fnb's n1 city branch on the 6th of May 2021 and they explained to me that i was given the wrong form. They then proceeded to give me the correct form and sent it away. (I have a copy upon request) One week later after still not receiving my money back I went into the branch again on the 13th of May 2021 to find out from the branch manager what is going on and they looked it up and noticed that nothing is done and that Nedbank still has not paid the money back. It is terrible to think that 2 well known banks cant be trusted with your money and that no one from nedbank has looked up what is happening in this matter. The atm has a camera which can confirm that i have not received my money that morning but it is also not that difficult to check the atm and and notice that it has R3000 that is too much and then check their records to see where the money should belong to. It's unbelievable that in todays age where electronic banking is becoming more popular that they cant be trusted to keep your money safe and the level of service that goes along with it, because i cant believe that NEDBANK has not yet sent someone to check the atm nor discovered that there is too much money inside or had the decency to respond to fnb's atm dispute that was logged on my behalf.
