FNB working with **********

I am beginning to think FNB is working with this VAR vh.... company because every month I have to go through unauthorized debit order with them and when you call FNB they give you the same number which never gets answered; the worst part is FNB constantly charging me for reversal of this UNAUTHORIZED debit order, how does this happen every month for a company that is non existent and where do they get banking details? unless it's an inside job and FNB making money from these reversals on top of their monthly charges is seriously annoying. You do research on the number and you can see it's ********** but banks not doing anything about it.
