Business Account

I am an FNB loving customer from the time i came to FNB from Another bank. the only problem i have with fnb is poor and humiliating communication. I have a business account with FNB and to be honest my company has not yet sky rocketed yet. I did work subcontracted to his company and he asked for my business account numbers so that he can pay for my services. thats only when i realized that my account has been closed without my notice thereof. And on top of all this is the same account that SARS is having for my submitted documents a month and half ago. so i went to fnb with the intent to reactivate my account but i was told its not possible then my question is: where is the convenience at FNB? With the type of treatment i am getting at my Bank(FNB) i think i should move to a bank where i am important as a customer. No notifications or whatsoever. The service sucks, its really a waste of time. Now how do i say my bank works for me? think of the procedure i have to go through with SARS and all my clients whom i am awaithig payment from
