Fraud in marriage

I got married to a girl in aug 2014 via registry marriage.We got married via social marriage in Jan 2016.Following which we started living together.But we started noticing unusual change in her behaviour and few suspicious activity.She left our house in april 2016 stating that she cant live with my parents.I started to visit her in her parental house to work out our differences.In may 2016 at her home i got proof that she had been married to other two guys .One registry marriage in 2010 .and another in 2015 via marriage in a temple.I had no information regarding any of these.I started gathering more evidence following which we filed a matrimonial suite stating the first legal marriage asking for nullity of marriage. And a criminal case regarding the fraud and threats she gave to harm my family and my reputation.Since then we lived seperate with no contact .I won the civil case as she never attended any hearing .so with exparte order my marriage was nullified.But she reppealed stating that she want to prove herself.so last nov 2019case reopened and the last verdict was vacated.She is again not attending any hearing .Due to this current pandemic everything have been slogged down.I found no way to get justice even after being cheated and victimized. Would like to know way out of it
