CAPITEC BANK ******** Debit orders

I totally agree with the other customers . CAPITEC BANK notifies you at anytime of the month that as soon as your SALARY gets paid into your account they will Debit you. But what is happening you get money from other sources for other things to be paid for and they take that money for their Debit order. HOW can that be legal or lawful, they should know that it is not your SALARY amount that was paid into your account, and since you are not in arrears and it is not your Debit order date. YET CAPITEC BANK takes the money from your account meant for something else eventhough your SALARY has not been paid into your account yet. HOW, HOW can CAPITEC BANK just do do that???
