Paternal cousins harassing us

Background : we are 3 people my sis, mum and I. My father passed away 15yrs ago. He was in IAF. We live in Rs. 20k pension. We had somewhat security or atleast felt secure until my grandfather passed away last year. Current situation: few days ago my sis and mum were at home at somewhere 6 or 7. I was out of town for some college work. My paternal cousin brother X started shouting abusive terms on both of my family members. Paternal cousin brother Y breached a grill which safe guard our rooms from them. We live on ground floor and they live on the 1st. They threw our belongings from garage. Hit my mum. The brothers X and Y's mother came and broke our bucket. Brother X's wife also shouted abusive terms. My sis has voice recordings and also 20 second video of them. My family went to police station they said not to lodge FIR, they will bring them and beat/hit whatever and make them give an apology letter (only the brothers) since everyone saying nothing can be done when 2 women fight even tho my mum didn't do shit. Been 3 days the brothers haven't made an appearance to the police or if the police is avoiding this. Also police said we can file FIR but it'll be of no use cause both will get instant bail. I am in dire need of legal help, please people help me. our home is same, we have 2 rooms and them 2 rooms but they use the garage and roof to full efficiency As of 4PM the police took them to station and the filed a counter case against us. I don't know what the case is also the station's 'chota babu' told us he has forwarded our complain but we don't have any recipient or anything We have video evidence of them being aggressive along with audios.
