FNB Banking Website Bug

I reset my banking password on the Mobile app. Unfortunately the new password does not work on the internet browser e.g. chrome, Firefox & Safari. So im able to do banking on the app but not on my laptop or pc. I went to the bank to get assistance with this buy i got the same grief. I tried, i don't know how many times, to reset my username and password on the mobile app but it only works on the app and no where else. FNB does not seem to know what is going on. I phoned them many times but it was a waste of time. Does FNB have IT support that can trouble shoot this issue. When i reset the password from the browser i get the message "No data returned". This has happened, i think more than 5 times of resetting the password. The banking system has a bug that FNB IT is not aware of. Im writing this to raise the issue here because seemingly FNB is not taking me serious about this matter. While visiting the Cape Town CBD one of the consultant intentionally selected a reveal password option when printing my password reset page. I have since logged a complain but have not hear the end or progress of it.
