FNB pathetic online service

My phones Battery gave in with the app on it. Try to put on new phone but have to authenticate with app. Phone ***** line and you talk to computer the whole time and have to authenticate with app. When get to consultant after more than a day they ask security questions of 10 years old about short term insurer that I can't remember and then tell you have to go to your branch to remove the device from your profile because you can't remove the app from the device without the app. Pathetic
