Blocked account

So FNB has decided to block my transactional account and not allow me to access my funds, all because of the mess created by MFC. I am busy fighting with MFC to rectify what they have done to my name. Now i need FNB to rectify what they have done, I need FNB to allow me access my funds as those are not proceeds from any *****ulent activity then i can go bank with another institution that would not treat me like a ******** without understanding what is happening. What fnb has done is a real inconvenience to me and my business. Allow me to withdraw the funds and close your account, I don't need this kind of services or treatment.
