WRONG FSL DONE SIGNATURE OF CHEQUE WITH CHANGED SIGNATURES

Hi, There are multiple threatening calls on my WhatsApp from different persons who are abusing me and threatening me. From what I have understood someone has given my number to them after their quarrel on a video game and they think that person is me without even knowing my name or background. They are calling and messaging me from different numbers. Their abuses are highly racial and they are threatening me with harm. I have filed a cyber cell complaint but nothing has happened yet. They have even abused my wife and threatened her after overhearing her voice from behind when I was on a call with them. I am looking for a solution where these guys are punished by law.

Hello. I reported csam to ncmec. Will there be a criminal investigation against me?

I added a complaint online on portal but made some mistake on it. I then did the complaint withdraw thing. But its status is showing under process. I have also given letter to local police for withdrawal. Will i be in any trouble. And will they contact me for withdrawal reason? Usually how many days does it take for withdrawal to be accepted? Should I send mail to some authority for better measure?
