Mbile APP Problem

FNB App sucks - the agent was good in terms of assisting me. I created a profile (had to do it on online banking not on the app as directed by agent) for my business account that could be utilised to access the banking application to keep personal and business profiles separate. After creating the profile, i logged onto online banking, it provides an incorrect password in the username field (really now). The agent trouble shoots on the banking app. Goes to Switch user, cannot see the business profile on the banking app. Then agent suggests we add a profile on the app. THe APP blocks the adduser field with the message oncall with banking app (same is experienced on her banking app by agent). Agent suggests to switch off WIFI data and utilise Mobile data. Brilliant i say , FNB app problem and I must incur data chrages. Guess what, when i do that the connectivity with the call is lost. So after 25 minutes, the challenge is not sorted , I found error in the app and incurred modible data charges. FNB the most innnovative bank with the worst customer experience possible. Every day FNB disappoints me
