Samsung is too bad company because it doesn't give android 12 update till now

There is no other company than Samsung which provides you the best of all.

Coming to your issue, your phone (Samsung A21s) will be getting Android 12 update in June 2022 (wait for few more days) as of the present Samsung's eligible models list.
