ABSA online banking APP issues

ABSA bank recently messed up the online banking App for iPhone users, which meant no online banking unless I deleted the App and started setting up all over again. The process was complex, and in the end the only secure way to do this was to go into an ABSA branch and get someone to assist. That took about an hour of sitting there doing it. plus the cost of transport plus the cost of my billable time. Other than a complex email telling me what to do (who knows if an email actually comes from the bank?), there was no real apology or explanation of why this had happened, and no offer of any credit on any fees, although I did not have access to the app for a couple of weeks. It was like "these things happen, join the queue over there if you want it fixed". I felt like I was at the mercy of a government department not a Private client of the bank.
