ATM Deposit Shortage

I have been with Capitec for a long time and satisfied, but on this one they are failing me. I was depositing 20k on the ATM. After I struggled, the consultant came to assist. But since the machine got stuck, the receipts only amounted to less R5900. He logged a call immediately, on the 21st yet to this day I am given nothing. It was only on the 22nd that there was an sms. 8 days later I call and whatsapp daily they just say they are waiting. Till when. It is money we are talking about and I need to settle with it. So disappointed.
