who is filing a case against this DW8, they just made my investment to zero, page-7

I mean this genuinely and with kindness even though it's a rough message.

The fact that you don't understand what's happening and need to ask for help on a forum is a huge sign that you have no idea what you are doing and are not ready to be investing in individual stocks. This is not a complicated issue - so if you're missing what's happening here then you are likely missing a lot more.

Anyway, the answer to your question is that DW8/KDY did a 25:1 consolidation.
