Mental harassment neighbor

I stay in kuwait and due to some reasons i had to send my son for few months to stay with his grandparents.Now because of covid he is stuck in kerala , meanwhile A Lady doctor and her advocate daughter staying in the flat below mine has been complaining about my 2.5 year son to child protection unit, Police and municipality. Its a new building with hardly 5-6 residents and no association. She had reported a child abuse & neglect case to DCPU,A nuisance case to local police a child sexual abuse case again to Dcpu.After investigations they were all found to be false. I counter complained to childline and when they checked with her she said she was getting disturbed by my child playing and crying so complained to authorities.She took an audio recording of my child crying to claim the sexual abuse.She next reported to Municipality chairman about an illegal shelter home being run at my house and we had to show all our ID proofs to prove that the residents in the flat my parents me and son are related.Next we get a call from MLA to check about a complaint to him by the lady along with her request to call the police and child line again.She has been smart enough to not give any written complaints but just call and ensure that all the concerned people just keep arriving at my door and pressure us to silence our kid. Now that all are convinced about this fake reporting by the lady what options do i have if i got to move legally against her?.How do i get some documentary evidence of the outcome of investigations done by DCPU, Childline, Police & Municipality.Is the daughter being a lawyer and the lady being a government servant liable to some administrative and legal actions.What do i do to stop this continuous harassment & can i claim compensation for all the troubles shes been putting us through.
