Dowry harassment

I recently got married. About a month back. I stayed with my husband for 15days and came back to my parents since my parents were travelling to native for two months. I started observing change in my husband's behaviour. He would stop calling or messaging me if he wanted to convince me for something. He would pick up fights for small reasons. And then one day he started fighting with me for not touching his father's feet the other day and he went on to talk about dowry and what was surprising for was my father-in law took the phone from him and started abusing my family for not giving enough gifts in wedding. After that day there has been no communication between the two family. My husband never bothered to call or apologize. My parents have spent a lot in the marriage. They never demanded dowry before my wedding and always maintained their stand that they liked me a lot and that was the only reason for the alliance. Still my brother gifted me a car and spent a lot in the wedding. Can i file a dowry harassment case or is it too early to think in this direction. I have known my husband for 6 months after I got engaged. He and his family never seemed they would treat me this way. Please help what is the way out what case can be made against them as this has cost us a lot of money and mental harassment.
