Stay away from this bank

FNB how many times must one complain with fnb before you sort out your system? 1)Our company got no credit or overdraft but FNB runs it into the red and then penalizes us for their bols up? I call it one word St@#$#%$ling. And this is the second time this year. 2) Then how many times must we do our FICA? we already done it 3 times this year with fnb but they do not capture, and the they will come and treatment us with closing and freezing our accounts because they do not do their work.....pathetic
