I am shocked with account closure disclaimer - Nedbank

Today I got a shock and surprise, for the first time in my life I learned that if you close your cheque account, if there are still open debit orders on your account and the account is closed. If those debit orders come knocking on your closed account's door, the account will automatically reopen in order to let the debit orders go through, and obviously your account will go on negative and you will be liable for the costs. If this is not cunning and a money-making scheme, please tell me what is it? Wow and wow, I am flabbergasted. And I got this shock from NedBank. I banked with FNB and Standard Bank, I have never heard of such. I am running out of wow's. I am shocked if not shook. I guess that was for first and last time I had cheque account with NedBank, never and never again.
