Absolutely frustrating!!!

I havnt been this frustrated in a long time!! My old device is gone in the hands of someone else and it's been a never ending battle to get my new device verified on the current device it just says not verified with no option to do so no matter what you try .... if you go online banking it says I'm not permitted to delink old and verify new for everything I want to do otps must be done through app on old device which I dont have so you telling me that the person with my old device is permitted to do everything on my banking and me account holder on the other end with a new device can do nothing please explain your logic as to how this protects me in any shape or form if this is the peace of mind fnb offers I must be banking with the wrong bank I cant do anything on my banking not even online can view translation history only for last 2 days that's it that's all I can do! Your self help is of no help at all and the best part is when the call centre tells you nothing they can do about it either!! So should I go find myself a bank that can do something for me and offer me full online banking services as seeing that when you get a new device you no longer get to have online services with fnb!!!
