Charged for Rejected debit orders

I understand they must get money as a business but not by being ******. They came up with a beautiful way of having us as their clients approve a debit order by using that debicheck thing but they still allow these *****ed companies to deduct unapproved premiums and when they can't find funds, Capitec benefits by charging R7 for insufficient funds, when you stop that debit order, capitec benefits by charging you for stopping, they are always on the receiving end! Im so disappointed at how *****ed this bank has become, I mean why allow a rejected debit to deduct! Im sure their shareholders are happy with their ill gotten funds, imagine how much they make by doing this to their every client
