Changing Systems without any customer communication

Capitec Bank is the worse at communicating with their clients. I have been using a username for my internet banking for the years I have an account with Capitec. A few years back they wiped my username and made me go to a branch to reinstate the username. They did this again a few months ago and told me to go to the branch to set the username. This week I wasted the time to go to the branch just to be told you can no longer use a username. How can you update your systems and change a user’s login details without any communication? They did not even change their login page which still ask for an Account number/username. I'm not sure how you can trust your money with such ***boys!!!
