FNB FREEZING ACCOUNTS WITHOUT WARNING

Does anyone know why FNB are freezing accounts without any forewarning? FNB have deliberately inconvenienced numerous clients and put them in very challenging and also very embarrassing situations. Imagine putting fuel in your car and then you discover that you cannot pay, because you can use neither your debit or credit card. And you have no idea what’s going on. To make things worse, they won’t assist you after business hours. So to hell with your circumstances. FNB’s explanation of non tax compliance makes no sense, when you know they have your tax details.
