Inadequate Service and Helpline

I've upgraded from an iPhone 10 to an iPhone 11. Subsequently I do not receive messages to approve transactions i.e. I was trying to assist my wife who received a new FNB Debit Card (Linked to my account), the approval screen displayed on my PC but never realised on my phone. I was told I have to verify my iPhone as a linked device. I get a message that it doesn't find the device? I call my "Private Banker" who told me he can assist if I answer a number of questions in a limited time, to which I agree. One of the question was how much my monthly account with MTN was. As I do not receive account on paper anymore, I had to consult my emails. We quickly ran out of time and he referred me to my branch after wasting my air time for nothing. One doesn't know the questions beforehand so it will take some time! I have been a customer of FNB since they took over from Barclays Bank and this is how they treat me in an emergency! I have tried every so called solution/instruction video on web from FNB to no avail! Service stinks.
