Not able to do something as simple as changing my number on the app.

They have a facility on their app to change contact details but after I changed my phone number on the app, my otps were still going to a phone number that I no longer have access to. I contacted secure chat to be informed that u would need to go to an atm to do something as simple as changing my number? I’m in the middle of an emergency, unable to go and fnb decides they’re going to limit my access to MY funds by making it impossible for me to do something as SIMPLE as changing my number so I can transact. There’s no security reason for this as my banking app is verified, I can provide my card details, ID and any other verification necessary. What’s the point of your app?
