FNB has violated my prviacy right and give my Business Bank Statement to someone.

FNB closed my Business accounts months ago, which wasn't an issue, however, they are giving out my Business bank statements to people, which is totally against the law. Why will you give my business bank statement to anyone? Was there a court order? What give you the right? Who give you the right? Why will you give my business statement to someone without court order, or authorization from me? Not even my husband can request my bank statement in my absence for it to be given to him, let alone you giving my business bank statement to someone that's not related to my Business, Company, family or employees, this is totally wrong, and we are going to take serious actions. Who knows how many people you have given it to? This is the only one that came to my attention.
