Wife left me along with child and is not reachable

I am currently employed in Hyderabad, where I relocated recently due to a job change. Previously, my wife, daughter, and I resided in Bangalore from January 2018 until April 2024, following a stint in Hyderabad where we lived with my parents after our marriage in February 2014. Unfortunately, conflicts arose between my wife and my family members, which led me to believe a relocation might resolve the issues. On April 7th, 2024, my wife unexpectedly left Bangalore for Parwanoo/Shimla, which is her parental home, taking our daughter with her. She mentioned it was for her summer break and promised to return after, but she has not returned to date. In June 2024, amid no responses to my multiple attempts to reach her through calls, messages, and emails, I visited them. However, they refused even to answer the door, and I only briefly saw my daughter once at the hotel where I was staying. Since then, I moved permanently to Hyderabad in August 2024 (due to job change), but their unresponsiveness persists. Additionally, I am increasingly concerned about my daughter's well-being and future, given my in-laws' reported financial troubles and their social isolation from friends and relatives. I am frustrated and anxious about not being able to communicate with or see my daughter. I have attempted to send multiple couriers and letters, but all were returned unopened. I am seeking your advice on the following legal actions I can pursue: 1. What are the steps to be taken if my in-laws continue to ignore governmental notices or any attempts for mediation? 2. Given the geographical distance between Hyderabad and Himachal Pradesh, what are the legal avenues, potential challenges, and considerations I need to be aware of as I contemplate taking legal action? It's essential for me to understand the appropriate procedures to undergo, especially as typical approaches like restitution of conjugal rights, mutual consent divorce, or visitation rights notices might indeed be ineffective given their history of non-responsiveness to external interventions.
