Lack of interest from Standard Bank

I have been a Standard Bank customer my whole life. I have been using the Android App a good couple of years now and have been very happy with it. It used to be easy and user friendly.

On 29 April 2020 I updated the App (like I've done many times before). So I want to log in and pay my rent... Asking for my password. No problem, I enter it. Then it brings up a screen about smarter way to bank. I'm happy to go through the steps, as I am happy with improvements... I click on start and follow the steps... At the end I have to enter my password again. A red block has been appearing at the bottom since then saying you have been experiencing problems.

I have a 1 star review on Play store. You rep**** and asked that I email my details to you, which I immediately did. That was on 30 April 2020.

Today is 6 May 2020 and still nothing. I can't check my balance, I can't pay people and I can't even buy airtime to phone you. I'm not leaving the safety of my home to go buy airtime at a shop to phone you to sort out your problem! How do you expect people to use your facilities if there is none?

Kindly can anyone get hold of me or EVEN BETTER... JUST FIX THE APP SO THAT I CAN DO WHAT I HAVE TO DO.
