Landlord Harassment — Physical harassment

I want to file a legal complaint against my landlord who is resident of 1st floor, house no. 27, shree ram colony, sector 4 gurgaon 122001. We shifted to ground floor in the month of july and at the time of shifting we had made it clear to the landlady that we may be moving out in 4-5 months. Now when we have to move out, her son, daughter and husband they are threatening us and physically abusing us and asking to pay money before we leave. There has been no rent agreement and they also did not take any security deposit from us although we were okay to pay. Now they have been harrasing us and we need to make complaints against the entire family.
