Business Account Closed without notification!!!!

I am extremely frustrated at this point where FNB has taken it upon themselves to close my business account without any notification. I havent received a call, letter, email or even SMS indicating that my account was closed. I leave all my business with FNB and when i really need it most, FNB eff's it up! It only takes a simple call or sms to avoid such issues. I am now left without a business account and cannot receive any payments from suppliers only because of *********** service providers. I wont use the all famous \Im moving my business to another bank"but i will surely make it my duty to raise this to the highest level of Management there is in the First Rand Bank Limited industry! I wasnt notified that my account was going to be closed! And i want my account reinstated with immediate effect!!!! I have contacted business banking and spoke with Shannon on the first call. I havent received any feedback since! """
