Dear Querist,
Way out from such unecessary litigation is to file a petition under section 482 of the Cr.Pc for the quashing of the complaint/F.I.R lodged against you without any substantial grounds. It can be quashed with the proper presentation of the circumstances in which these complaints are lodged just to harass the accused(you). According to me, after getting the complaint quashed you should file a defamation suit.
As asked, the next steps you should follow are:
1. Filing a quahing petition of the complaint/F.I.R
2. After the quash, filing a suit for harassment and defamation.
hope this solves your query.
You can contact me for filing the quashing petition and defamation suit.
Regards,
