Absa Cash Send

On the 18 June 2021 I recieved an Absa cash send. I went to the East London Oxford Street branch atm to withdraw the funds. The atm gave a technical error message said the slip said it will be automatically reversed. I enquired at the branch they told me it will be reversed. I called tge sender to inform and they informed on their side it shows money was redeemed at 11:53 which is the time I was withdrawing the money. I called and e-mailed Absa with no positive outcome. I still haven't recieved my money and no reverse has been done. I don't know what more I must do to get my money.
