Missing money from the account

I have an issue with your banking and also your bank statements, there seems to be a transaction that came through on the 26th of July 2019 at 00h00. However this transaction does not appear on my bank statement for the last 7 days all the other transactions seem to appear that had occurred on the day except this one transaction for the amount of R1472.

I cannot get through to your call centre to get assistance it is forever ringing with no answer.

I need assistance to track what happened with that amount of money missing from the account.
