FNB- how can we NOT help you, that should be their actual slogan

Unprofessional.. Not helpful.. Don't Care.. There are many more ways that I can describe FNB and the services they offer, but I don't want to be rude. 15 June, when I tried to withdraw money from my business account, I was unable to as my account had been frozen, with no warnings given. I received a notification from them only 1 week later informing me that my account had been frozen. Not once was my new business that is now suffering a big loss taken into consideration. The customer who had opened the case, received his goods he paid for. Now because FNB is struggling to get this customer in the hands who at first initiated this, my business still is suffering. I have phoned them numerous times, emailed them. The reply I keep getting is the same everytime, I must be patient and wait. Why couldn't they tell that customer to be patient and wait for the delivery, after all, I received payment from him and two days later my account was frozen. He has now received his goods, to which I provided FNB with the necessary proof, but I'm still being put on hold when it comes to my account and business. I am very disappointed and unhappy with the services FNB is giving to their own clients.
