FNB: Utterly uselss and aggravating!

Twice over the last month, when I have tried online to make a Notice to Withdraw on my Interest Account, an error message is displayed telling me I cannot manage my account and I should either contact the number provided or use their most marvellous app, which allows to me to do anything I need with my accounts, anytime, anywhere. What a crock. The app does not allow me to make a Notice to Withdraw, leaving me the only option of phoning through. Now, thanks to FNB's "brilliant"security measures, I have to provide my credit card pin to verify it is actually me wanting the money. Yet when I provide the pin I know to be correct, the annoying automated system rejects it and deactivates my card. So now I can't access my funds and my card has been deactivated! Then I am told to go to online banking, access the "My Cards" tab and choose the option to review or change my Pin. I do not have that option, only the one to Cancel my card. So for whatever reason, my online banking doesn't even provide the most basic of options that I am supposed to have at my disposal. Now I have to go into a branch not only to reactivate my card, but to do a Notice to Withdraw. And it seems that they aren't going to get this online banking problem fixed, which means I am stuck going into a branch each time I want to access my savings. This is an absolute farce! "FNB: How can we help you?" Why don't you get your useless system sorted out? FNB is actually beyond help. I am absolutely fed up and furious. USELESS BANK!
