***** in my account

I've been watching my account for sometime now. There has been some debit orders going out of my account without my consent, this leaves my account in a minus, and these have to be paid by me to standard bank every time . I don't get paid on the 15 so I don't know who gave permission to them to debit , I am currently under debtreview and cannot afford to pay these amounts and I cannot even open a new bank account to change since standard bank cannot do anything about it. I was told about debicheck and that doesn't work on these debit orders apparently so why introduce something that cannot help your customers?
