Unauhorized debit order

Good morning This morning I went into my Standard Bank account and noticed the an amount of R2512.22 was deducted from Capitec Bank out of my account. I phoned, Capitec Bank 3 times before getting any result, asking why money is deducted by debit order from my Standard Bank account. The lady inform me that is was a credit card payment (Capitec) from another client and my banking details was given for the debit order??? How does this happen????? I have forwarded the bank statement with the debit order amount showing to Capitec Bank requesting that the debit order is reverse immediately from my Standard Bank account.

I rely on every sent that is in my bank account for living costs, and if there where no money in my Standard Bank account I will be penalized for Capitec Bank's mistake. This is not acceptable at all, and I need an urgent response from their side
