Standard Bank online poor service

Wow, standard bank app / mobile service is really terrible. I have been unable to login for more than 2 days. then pin and password are all correct, but I get the message "something went wrong, please try again later". I tried to call the online banking services and I was on hold for more 45min and still couldn't get through. mind you, this was in the afternoon from 14:00 to 14:45. I tried to call the private bank service and they couldn't assist as well. I am considering changing banks
