Illegal Ternination Query

I want to complain few of things which I am facing during my working in HR & Admin Dept. I joined this org. for learning and growth but in respect to that what I have experienced is that I have faced lies, disrespect, harassment and many more things that even one cannot imagine in such a period of time that too in a same dept.I joined (company name) as Supervisor- HR & Admin in Dec’17, who has to assist HR and Admin team. I started my assignments with confidence and passion but simultaneously I have been asked to change my role & responsibility by my reporting manager (HR Head) almost every alternate day. First day he asked to supervise HR & Admin team but next alternate day to stop doing so then again after few days he repeated the same things and so on.The assignments which I took over were very good but as soon as I finish them my reporting manager (HR Head) called to stop working on them and hold them purposely and when it got delayed then deliberately put all causes on me.After one and a half month without discussion or intimation he asked me to change my roles and responsibility from HR & Admin to Admin only and asked me to replace Asst. Officer Admin who was 3 grades junior to me. When I asked for causes, reasons and requested him to keep my profile with HR & ADMIN then he threatened me and me do so or leave the org.. Due to no job in my hand I started working on Admin assignments. Also one day he changed my work station because I did not take alcohol with him and did not accompanied him in a seminar and continuously created problems in day to day assignments. I keep on working on my assignments by avoiding such all things but now he has crossed his limits.I don't know what insecurity he has with me, he stares at me badly and deliberately try to trouble me directly and indirectly by telling lies. After noticing his habit of lies I started to take everything on mail, which he again opposed and scolded me for asking HR & Admin matters on mail. He prepared my Termination and Full and final settlement just one month before of my confirmation date and harassed me like hell and pressurize me to leave the org.. Prior to that also he tried to attempt to show my working ethics unethical in front of management but due the proofs I managed and prove my sincerity.I worked very alertly but in spite to that he tried to terminate me without any legal grounds or prior discussions. When I asked for legal grounds then he again threatened me by taking Management's name and pressurize me to leave the org. same day. In this Termination matter all the HO Managers came in-front and oppose his action. after facing this mental stress on daily basis I choose the option given by senior management to change my department from ADMIN to IT and look for other options but after just 1 week of my transfer he again started tourchering and keep on going regularly to IT head for asking my resignation and last day of working.He also blocked my confirmation and appraisal.
