EFT reversal or EAP recall

Hi. I need urgently assistance!!! the call centre tried to help, but OBVIOUSLY couldn't. My husband transferred R800 from his Std bank account to my Std bank account - INCORRECTLY at 7.15 this morning!!! I phoned the call centre at 8am. I am not using my Std bank account as paying off my overdraft. I NEED this amount reversed to his account urgently, but no-one can help me. I was told they can do and EAP recall, which takes 10 WORKING DAYS AND COSTS R290, but was later told, it cannot be done, due to the amount being allocated to my overdraft already. It is totally RIDICULOUS, THAT MONIES CANNOT BE REVERSED IMMEDIATELY. I CANNOT USE MY ACCOUNT, DUE TO PAYING OFF MY OVERDRAFT, SO I CANNOT TRANSFER IT BACK!!! Now, I am told to go to the bank and sit and wait for assistance!!! I do not have time for this!!! Please assist urgently!!! I CANNOT TAKE CALLS DURING OFFICE HOURS, ONLY COMMUNICATE VIA EMAIL
