FNB ACCOUNT FROZEN - NO REASON GIVEN

FNB JUST DECIDED TO FREEZE MY ACCOUNT BECAUSE THEY NEED SOME FICA DOCUMENTS. WHY DON'T YOU WARN YOUR CLIENTS BEFORE YOU DECIDE TO HOLD ONTO OUR HARD EARNED MONEY. ITS A SIMPLE CASE OF JUST ASKING IN ADVANCE -WHAT GIVES YOU THE RIGHT TO PUT AN ACTIVE ACCOUNT ON HOLD?? THIS IS PATHETIC - YOU GUYS ARE GOING BACKWARDS!
