Not helping with unauthorised debit orders

<p>I was unemployed since beginning of May 2017, since then there has been 5 unauthorized debit orders (that in my mind constitutes *****) going off my checque account. I have spoken to my bank about them, but they have done nothing to help me block them, just keep on charging me a debit order return fee that has resulted in over R1500 in charges, instead of blocking the debit orders as my request was.</p>
