Call from Women Cell for counselling

I found a match on Shaadi.com. We were in relation for an year and we married in June 2018 and lived in Mumbai. Wife's nature took a complete U turn after marriage. From being polite and soft-spoken, she turned to be highly abusive and she used to get kind of Rage attack for pity issues and used to ran away at her sister's place who also lived in Mumbai itself. She used to stay away for 2-4 weeks and then returned. There were many issues due to his behavior between us. In Feb, 2020 she finally left matrimonial home with all belongings. I have sent her a legal notice after that but no reply. Now after almost 19-20 months today I got call from Mahila Police officer from Mumbai for counselling. I have many call recordings of her abusive and threatening behavior and also have done some NCs at local police station about it. Please let me know what should I do now.
