FNB Mzansi **** continues

After months of having money disappearing from my account thinking that it is just normal bank charges, I decided to request a statement. It came as a shock when I realized that there is an unauthorized debit order from some company by the name of "Mzansi" and what is really alarming is the fact that these people have my ID number. I told a friend about this only for her to tell me that she is experiencing the same problem and she called FNB but got no assistance. I then tried reversing last months debit and it was successful but when I tried to dispute the other debits online the system would not allow me. How is it possible that so many people complain about this **** of a company but FNB still *******LY approves their debits?
