Formal complaint against standard bank

I am very unhappy with the banks decision as it has really disadvantaged me. I have gone through the banks findings and I find it very unclear and would like the decision to be reviewed on the basis that it was not due to my doing but ***** occurred within standard bank, a staff member of the bank did an early repayment of my money from my notice deposit and sent through the funds to my cheque account where ********** were able to have access to these funds, I need the bank to provide me with logs of how my money was taken out from the notice deposit to the current account. Secondly, I find it very interesting that I reported the transactions within the same day it had happened as I noticed my current account balance was not the same, these transactions were still outstanding card authorization and the merchants that debited my accounts are international and it normally takes about 2 business days, why did the bank not cancel authorization? I feel there was still ample time for the bank to have done something as I noticed something was wrong earlier. My one-time pin was sent to my number and then authorizing of the transaction was done because there was a sim swap that was done **********ly with Vodacom my service provider. I opened a ******** case with the Saps. Lastly the bank concluded that my money was taken due to vishing/phishing ****s where my card was not used, how do I know that if the finding are not presented to me as evidence, can I please have a sense of security and logs also be checked and provided of staff members that accessed my profile 24 hours prior to the ********** transactions happening.
