Vodafone — VI App crashes

Hi,
I have been using VI app to manage my prepaid profiles for past year or so. The app forcefully updates itself. The recent update v9.8 crashes and the icon disappears from the home screen on my redmi android phone.
I reported this issue with screen recording to vi support.
They are fooling around. They are not ready to solve the issue.
They want me to test it out in another phone but no one is obviously ready to lend me their phone for this reason when the app in question is unstable.
VI is not solving the issue.
VI lacks accountability, ownership and commitment in first place.
BAD
