debit order wrong account

I have a loan with Capitec and they suppose to deduct my debit order from my Standardbank. Instead they deducted it from my Capitec. I never gave permission for this, this is ***** taking money as they want from whatever account. I'm busy going on debt review and I'm moving into my new apartment tomorrow. Now I don't have my deposit!!!! Surely I can report this to the Ombudsman or how ever but I will not leave it here.
