Absa
CANNOT REVERSE MY OWN MONEY BACK

I paid someone via EFT and cannot get hold of the person, who is ALSO an ABSA customer. I want my money to be reversed back into my account. Now I get this response:

My question is WHY can a DEBIT ORDER be reversed but not an EFT payment??? what If I pressed a wrong button on the account number???
