Utterly *********** IT people who haven't a clue about UX

I've been caught in a loop where my FNB phone app needed to be upgraded.

Simple transaction, right? NO! When I went to update it in the App Store, Apple told me that I needed new upgraded IOS. So I clicked okay. No chance! A message from Apple says that I cannot upgrade to latest IOS because my 3-year old phone can't do it.

So I go to the FNB website. I log on and try to do a transaction. Sure, they say, but now we need you to verify that your transaction is valid - on your phone app! You have 90 seconds to do that. I go to my phone app, and get the same message: "This app is out of date, and needs to be updated." Round and round in circles.

Now I'm in a ludicrous situation where I am using my son's phone where I reloaded the app, and will only be able to use it when he is near me.

I know IT people are supposed to be clever and all that, but my opinion is that they are utterly clueless. I'm 64, and I don't need this stress in my life. And especially not since I have been a client since 1965.
