Design Critique: Airtel Direct To Home Service – Web Portal + App Feature

I have often wondered if a telecommunication company of such large scale business doesn’t realize the errors of their website, and corresponding actions on the App, which is part reason why I conclude it could also be because of a (read lapse in) responsive design that has not been streamlined for different devices, in my case an Apple MacBook Pro M1 (2021), and an iPhone XS Max (2019). I also feel the devices that are discontinued and also the older Apple devices face Usability issues often because they fall out of the designer’s consideration category. This is a big problem that is often being left unanswered in the digital domain, and it’s not a new one, but a recurring case. I’ll explain why.
