Capitec AEDO transaction reversal

I have a Capitec account which I transfer money into every month. On 25/08/2021, an amount of R3000.00 was deposited into my account. After a short while an amount of R2664.13 was debited from my account. I contacted the Capitec call centre, only to be told to visit the branch for a dispute because it is an AEDO transaction from African Bank. I contacted African Bank which confirmed this was not their debit order because all my account are fully paid. All I want from Capitec is to have the money reversed because I do not know the credit provider who debited my account.
