Dissapointed support on suspected fruad case

I am very disappointed in the feedback and support i got, i had made 3 separate international payments to the states over a course of two weeks. Total amount was around R950 000 and reliazed within the 30 day window that this was a ****. I asked to return the money and got feedback that the beneficiary account do not have the funds. I then asked for advise or how to report this issues as i lost a huge amount of money and the reply was " This has been referred to our Compliance management team.They have advised that the matter will be placed on record with the SARB, however there is no further assistance we can provide. Furthermore I have provided them with all the information they require" is there no way that the banks can see in an account is suspicious. How can i escalate or who to get involved to try and get this money back
