Unauthorised Journal debit.. No consent

I am extremely disappointed with the inhumane manner that ABSA conducts its business. My account was debited for an amount of R10755.43 yesterday on 25/05. I have never consented to such a debit on my account. I had a personal loan with ABSA, but for them to debit such an amount is extremely poor practice on their side. I called the bank and was given a number to phone some attorneys, when I called the attorneys they advised that it wasnt them who debited my account, but it might be ABSA. SO even for them to give me the run around and send me to call attorneys when the debit was on their side, is cruel and unfair. I need to have that money refunded to my account ASAP as I have bills to pay. This money was debited without my consent. I am very disappointed in ABSA and I have always held this bank in high regard. I need answers.
