Poor communication with clients

I have been banking with them for years and for the past week and a half my Nedbank app stopped working, eventually called the call center before deciding to go to the branch and was told that my app has been ''discontinued'' . Nedbank did not communicate with me or send any notification that we now have to use the money app and the old one is being phased out. and if i had not called to ask what was happening with my app, till today i would not be able to access my app!!!
