ABSA App lost security settings during IOS update - no easy way to resolve

ABSA mobile app lost all its security settings during ios update. When I phoned the help line, they told me to phone the branch (business account). When I phoned the branch they told to visit the branch to have the problem fixed - as if all their customers have nothing else to do... This is ridiculously poor service to expect customers to take hours out of their busy days to fix problems caused by their poor app technology (no other banking app lost its settings during the ios update). In the mean time my business came to a standstill - unable to make payments to suppliers.
