ABSA uselessness and unreliability

I have tried emailing and calling and ABSA has NOT helped e resolve my banking app issues. I cannot pay my accounts due to a prompt required from the banking app, but as I cannot access the app I cannot pay. The tech support is utterly useless and ***********, they do not listen when I explain that I have done a certain process 3 times over and then they tell me they will phone me back, 3 weeks later and I am still waiting for the phone call. I have sent various emails, I have tried to be patient but this has been going on for more than 3 months and is UTTERLY unacceptable.
