Help me guys

So I 19M filed this cyber compliant about someone doing something inappropriate to me online.

Coincidently she was a girl but NVM

Now the police called me after 4 days Askin me the whole scenario. I did that Now they are getting lazy and don't wanna try to investigate

Maybe because I'm a child ?

I've seen in movies where a lawyer sends some notice to police station and they immediately approach the case

Is it true ?

Also I don't wanna go to PS over an online complaint. Please suggest me some real steps to get things done
