Unauthorised debit order

So today I find out that So Music and Rescue Box are each happily deducting R49 each off my account without my permission. We worry about Nigerian ****s yet out banks just allow any debit order to run off anyone's account without their consent. It is just crazy! I want ALL my R49's back from both Companies. Does Carte Blanche not think it's time to take the banks on over allowing debit order *****? People are becoming rich by taking money out of people's accounts and hoping they're too stupid to notice (and unfortunately some people are). I wonder if this is a world wide problem or only in South Africa!!!!
