Sexual harrassment at workplace

My senior calls me to his chamber alone and talks about with me. Later also he unnecessarily calls on phone and in his chamber in pretext of work. When his advances are not entertained he started creating hostile work environment, bad mouthing about me and sending deceiving report regarding my work performances and questioning my ability for the position I was holding. In official meetings and even in his official communications he addresses me as ‘dharm patni’ of my husband’s name, instead of referring me using my name and the designation I hold. When I proceeded on child care leave only after getting the leave sanctioned by proper authority ironically on recommendation of this senior, he was writing in official letters that I am unfit for the post because I was using the leave( which is granted to my child as his fundamental right Under article 14) as as an excuse to not work. He tried to unofficially get access to the cctv footage of my office chamber. He had his people stationed at the gate of my residence where he got me clicked with my knowledge when I was leaving home and kept track of my movements. I informed the head of my office about this sexual harassment and gave a detailed report of the gender discriminatory behaviour and hostile work environment that was created by that senior for me, a two member committee was formed under POSHW Act. But neither the committee was formed as per the guidelines of the act, nor the rules and principles of natural justice were followed: 1. The committee consisted of only two member both from the department. 2. Despite my repeated requests the man continued to be on the post and using his influence and power he had been able to influence the whole investigation and he had coerced his subordinates to be witness in his favour. There are clear documental evidences to prove that statements given by witness are false. 3. While I was transferred from the post, but that man continued to hold a very senior position in that organisation I could manage only 2-3 witness in my favour (all very senior level officers), but their statements were not taken into consideration and the man was given clean chit.
