Loss of income

I am really really flippen disappointed with fnb and I will continue rating it one star, if I could I would give it 0 zero. I lost R1600 because my bank account was on a minus which even today no1 has bothered to call me and try to assist me. This bull**** is totally unacceptable....I want my money amd someone will have to call me or I will continue rating it zero.....
