Core functionality of online banking is a joke

Never a dull day with FNB .. a limit I set pretty high for online xfers has somehow reverted .. i cannot xfer money between accounts of mine .. the iPad application wants to take selfie of me which will be compared against records in Home Affairs ! When I try to update my limit after successfully logging in a browser I get :

Some errors have occurred... (E-90909) Limits Service currently unavailable

I am giving up ..
