Debit Order #HDLTRADIN HDLTRADINGP***xx0820

I also have experienced this on an ongoing basis where amounts as large as R350 at a time is being debited from my bank account. I have no prior knowledge of using any company known as HDL Trading and I would like if someone could assist with identifying these debtors as it becomes very difficult when such an amount is debited with no reason as to what service I've been offered.
