ATM malfunction

On the 2nd of January 2020, I made a cash deposit of R 150.00. The ATM malfunctioned while depositing the cash and the process was not completed, resulting in my funds not been able to be allocated to my account. Till date I have had no contact from Nedbank and no refund of my lost funds. This is **************** and unacceptable. Please rectify ASAP. The reference number I received for this case was ***8.
