Poor service

I have been calling FNB call centre with no help about setting up my FNB app when I try to register I get PAIRING ERROR message I've been told that two profiles were registered ,the other profile cellphone number is captured incorrectly with prefix according to the call center consultant upon opening savings account then I need to go to the ATM to update my cellphone number to fix the prefix issue once that I would be able to register on the app. I called in again and I didn't any help I'm very disappointed. FNB is always on about their fantastic digital systems I am not impressed.
