Unauthorised Debit Order from Unknown Companies

I have stopped 9 unauthorized debit orders in my account from unknown companies from April this year until now. Every time I stop the debit orders they promise to investigate and come back to me but they never do, all I see is another debit order from a different unknown company for R99.99. After I have stopped the debit orders FNB still charges me a cancellation fee..... for what??? I am not the one who authorized the D/O so why must I pay a cancellation fee??<br> <br> FNB cannot explain to me how and why do they load debit orders without my consent. They can also not tell me who these people are.<br> <br> I am so tired of 'policing' my account each and every month. The answers I'm getting are just useless because the very next month the same thing happens again.
