My accounts has been frozen because of a personal vendetta and fnb allowed it to happen.

I have been using Fnb for more than 3 years for my business banking. One of my clients who happen to work for fnb reported me for ***** of which we have a signed service level agreement which was supposed to expire on the 27th of October end of business, but to my surprise my account has been frozen because of a personal vendetta as well as a way of controlling how I conduct my business. My biggest problem is this client has made a series of payments in the last month which I invoice for and we're never *****ulent. This bank doesn't protect its clients and I am very disappointed and dissatisfied because fnb has made it not possible for me to adhere to my side of the agreement. Without evidence they managed to interrupt my business as well as the commitments I have with my clients. Immediately this is resolved I am closing this a count
