ATM lost cash deposit

Hi <br> <br> I have made two Standard Bank ATM deposits for school fees in March to the school account which also uses standard bank. The school has come back with non payement letter for March claiming that they have not received the funds. Unfortunately I have lost the receipts.<br> <br> Is there a way of tracing this issue within your system. I do have the reference number and the account details of which the money was deposited to. <br> <br> Regards<br> Your help will be appreciated<br>
