Termination of Account.

I am writing concerning the termination of my business account with Fnb. I got an email giving me a date to terminate my business account for no reason. Nobody reports my account. I have never violated any rules but still they wanted to close my business account. I have been banking with Fnb since 2014,Is this how you treat a long-time customer even with the little I still contribute to the growth and development of your bank? This termination will have a huge effect on my business because I don't have another bank and I can't open another bank currently because my business permit expired in FEB, And I did submit another application which is not yet issued so doing this to me now is like killing my business because mostly I deal online with my customers which require payment to be done electronically.If they can wait for me till I get my permit I can open another bank, Also by doing so can affect my permit application as well because I included my account statement on my application and I will willingly close the account myself. The termination of the account will kill my business which I don't want that to happen.
