Stupid debit orders

Banking with standard bank is becoming a nightmare. For the past months have been having, 2 many unauthorized debit orders. They dont even bother blocking them, they just charge you. There was a shabir debit, slz and now Dazobase Dazon. Stupid names, debiting R98, R97. When you tell them to stop them they'll tell you about leaving money on the account and reverse later, like we all have time and airtime to call them and reverse. I dont save money on mu cheque account and sometimes thwy gwt unpaid and i get charged unpaid debita amount for something i didnt authorize. Where do this people get our bank details? Standard bank gives them. I'm tired of this bad service. Even today samething happened, I'm sick and tired of always monitoring my account for stupid things.
