Fnb ( worst national bank)

Fnb the worst national bank as their customer for over 2years I'm disappointed in the way they conduct business always trying to rip people off even when they have nothing my account now Has a negative balance of r4000 after I lost my job due and now I have a new job and only to find out I cannot used my fnb account because I now owe fnb 4000 in charges for the past three months that I dd not have a job how is one expected to pay such an amount in charges its crazy and I was looking to forward to using my cheque account again but now will be taking my business elsewhere and this is not the first time I have had a problem with charges with fnb they are the worst guy please choose your bank wisely don't just bank with any bank that will rip you off even when you are down I don't have 4k for charges when I'm just getting up on my feet they don't even deserve one star review
