My Relatives Are Not Allowing Me To See Or Talk

Since last 8 months, my relatives including my sisters brothers, are not allowing me to see or atleast talk on phone with my ill parents, whenever i ask them for allwing, they are making false excuses. 3 months back, i heard my uncle is bringing my father to hospital, i told my cousin bro tht i will talk to father their. Since then, uncle hvnt brought my father to hosp. Also he is showing false dmsympathy to him and decreasing my character towards them telling them liea abt me. Also he has taken my fathers 6acre farm, saying, mai kheti karunga jab tak k aap beemaar ho, also i talkd with my mother in my grandmothr home, she lookex afyraid pf someone she was not taking photos of me, i shown this to my moms brothers their, they didnt care bt it, also someone called them too warning them tht if they help me, my uncles will make false case against them, what to do in this situation to fully get my parents responsibility.
