• How can I solve the land disputes

Dear Sir,
I am Subhankar Mondal. My address is Village-Debipur, PO-Kundarali, PS-Baruipur, and Dist –South 24 Paraganas. West Bengal-743610. With due respect I would like to inform that due to my work purpose I bound to stay outstation. My old age parents are staying at home they are on their seventies. My father is a Retired school teacher and mother housewife. 
From my childhood I know that our area (Kundarali)  has a land dispute. And several land survey happened by local surveyor (Amin) for so many times (at least 17 times) for the land including my land (our residential house also their).  Each time there we found different different solution. Several times my area comes under my neighbour’s area or vies verse. Its increases local tension. Basically we are non political. Actually what happening each time if my area comes in their place, they are fights with us and not agrees to leave land and if their area comes in our land they puts pegs their and increase their area in our land and they make a boundary wall. Till date we could not able to protest because my father very introvert type person and not so talkative and afraid from such kind of clash as these people are basically rowdy type. Till date its continues like this.
Other things that two roads coming beside my house one east side another south side. 3-4 times the east side road widens and the widening happens only our side because these rowdy people staying other side.
During 1st time of widening due to political pressure we removed our boundary and open space for widening purpose but its not happens other side.
 Very recently what happened, that east side village road development process started its converting to bituminous road from a brick road under of gram sadak yojna. But this time also its widen in our side not the other side its broken our wooden fencing and that rowdy people threatens my parents that our house is a illegal structure and its comes on road and the district magistrate of South 24 paraganas is her friend. Just one phone call and she can destroy our house. If my parents try to make any fencing or boundary wall. She will destroy our house.. this comment made by Miss Depa Bhattacharya. There are 3-4 people also with her ..these are Her uncle Mr Khokan Bhattacharya, Her 2 brothers Babla & chottu (don’t know actual name), and our back side land owner Mr Partha Naskar and his son. 
They torturing my parents in several way by pour their coal factory (Paratha naskar has a gul / coal factory) polluted water in to our pond. Throwing rotten rats in our land, throwing stones in evening targeting our glass window (it’s happened several times). We several time did the land survey with the help of gram panchayat and with our own cost for solve the land dispute. But our surrounding people not want to solve this.
I know that due to jealousy this people are doing this. They want to crock our land. I want to know how we survive in this social condition. How I save my parents. To whom I complain. I am every time afraid about my parents thinking mishaps. They are now mentally and physically broken. Due to this my father and mother are now patient of high pressure and blood sugar. I beg to request you that please save us or suggest me how can i save my parents.  Lastly I want to inform that if any mishap happens above people will be responsible. 

How can I solve the land disputes
Yours faithfully
