Banks are failing Entrepreneurs

I opened a Business account on 18 June 2018, to what I was told that the account is inactive and whenever there will be money comes into the account I must just come to the bank and notify them on this 2 years 11 month trying to source for business and nothing was promising. I finally got just a small project to render my service to and now since FNB told me to come to the bank when there will be money deposited in my account. Yesterday at Bedfordview Centre I was told that my business account was closed. No one communicated with me no SMS nor emails, now the department that I provided the closed business account what is going to happen because I can not send money back after all the hard work I did and FNB failed to be transparent with me because of their Consultant who didn't mention upon the opening of the account that is given a certain period of time. And nothing in black and white indicates that and how does a service provider go ahead with the closing of the account without any communication with the company Director. Our economy is so bad we trying to make a living out of nothing & whilst trying we are taken for granted.
