Debit reversing issues

From reading below it clearly shows that Capitec does not have the customers interests at heart but rather the creditors. My issue Is with reversing an early debit from my sisters account, she went to the bank to ask them to reverse because this debit is only for later this week and the money I sent her is for something important, Capitec Chatsworth in Durban said they cannot. I deal with Fnb and never had any issues reversing or disputing debits. How is she to pay her rent now that the funds are gone???Is this Capitec policy ,irrelevant who takes your money and how they do, whats done us done... you just suffer
