Capitec ATM stole my money. Incorrect ATM deposit counting

I deposited 25000 at a Capitec ATM. The branch was not taking in branch deposits so I was forced to use one of the ATMs outside. The ATM short changed me a whole R3900. I had R25000 to deposit after making sales for a business. The ATM kept rejecting some notes and returning them. The Service agent told me thats what the ATM does that I should be patient and keep putting the money in. I kept putting in bank notes, whenever the ATM showed the total of the notes it had accepted at a given time, I accepted it. When I was tallying up what was reflecting into my account it did not add up to the money I put in. I had 25000 to deposit, only 200 was not accepted. I should have had 24800 worth of deposits reflecting into my account. But only R20900 before the charges reflected. I logged an incident and their response was "your claim was declined no errors were detected from the machine and the money was not found". Nothing other than this. I had to use their whatsapp line to get this information. I am very dissapoitend and heart broken at having my money ****** by Capitec bank. I worked so hard for them to just my money. And there's been no other correspondence to explain what investigations they did to arrive at their conclusion. If I can put negative stars as a rating I would.
