unauthorised debit orders continues after complain

After complaints were laid about unauthorised debiting of my account and knowing about the 99 Rand **** FNB still allows these debit orders and don't even contact a person to find out if this debit orders have been authorised, people are losing money and FNB are doing nothing to keep people's money safe yet that is the reason we open up bank accounts. In these though times where people are suffering with economy they must lose money to ******* and the people we trust in keeping our money safe are failing us. Or are the people who supposedly checking on these things involved in these ****s. And also FNB allows these debit orders and then they still charge you to stop it, this is really pathetic service being a client for over 20 years. They need to get this sorted out asap
