FNB system blame.....

I had money be paid into my account,for emergency. I now have no money in my fnb account,i spoke t ***** consultant....as per consultant its a system issue. More like some agent stole money from my account and they say system is faulty and has not updated yet. Just suddenly......a set system cant do anything without instructions. Now i have no funds to buy my son bread for school,or enough petrol for rest of the week due to fnb incompitance.
