Nedbank wants me to pay R50 to prevent every R99 from being ****** from my account every minth

So I notice a R99 debit from my account with a reference VAR VH VAR***XX. when I went through my monthly statement I noticed that this debit has been happening since March 2017. when I called nedbank to inquire and revers these debit I was told I can only reverse of the debit, when I requested nedbank to stop these debit I was told I will have to pay R50 for every debit they stop. Alternatively I'd have to trace the company myself and try to stop them from debit my account. when I try to call South African Payment Exchange(the company debiting my account ********ly) - ********** I get no answer.

I have an issue with the fact that I need to pay a fee protect my account from known *******, this means I that have no control on my account and from Nedbank's response neither does Nedbank

Be warned!!!!!
