Debit order

26 May 2015 I received a notify me sms fromthe bank that R350 has been debited from my account from HDL Trading i called the bank i told the consultant that this is *****lent and i have tried to call the company number dont go through i asked the consultant to stop all debit orders from this company as i dont know who they are. The consultant promised that he did actually activate a stop order. 27 May 2015 i receive another sms from the bank notifying me that another R350 has been debited. I call the bank again the *********** consultant rather asks me to change accounts how would you even suggest such.... i feel standard bank does nothing to assist their clients or protect them from *****. i wonder why the debit order still went through after the consultant promised that they have activated a stop order
