ABSA banking app update problem

I am experiencing difficulty with the Absa banking app after the update from1 March 2018. The app is not logging into banking and freezes just after trying to sign in,it displayes Absa in the middle of the screen and just stays like that. I gave a review through google play store after which I was contacted via email but still no resolution. Then I tried the Absa action line,,,,,,,what a disaster. I explained my problem and was transferred. I tried to explain to them that there is absolutely nothing wrong with my handset or the network and that I have uninstallled and reinstalled the app,they just simply dropped the line. This morning again I tried the action line,5 calls later and eventually someone actually talk when they answered the phone. Still no resolution,app not working and cant do any banking whatsover as it can be approved with app not reponding.
