Mental harassment at workplace. What legal action can I take?

I am in administration section of a central govt. department. My section put me under heavy workload of multiple seats. I told them that it would not be possible to handle by one person. Still they didn't listen. Definitely my work resulted in lots of mistakes. Then they issued me a number of memo (memorandum). Then I protested for issuance of memo to me and asked for change of section. My director is a harsh lady. She got angry on this. It has been only 6 months in that section. They made me write an application that I want to change section. (As per my department policy, no employee can transferred before completion of 2 years at a seat. After that they transferred me to a far office in India. After that I stopped going to office. After 2 months they relieved me from their office and sent me relieving order with order to join in that far office. I refused to receive the orders from postman. Now they pasted those orders all around my house. I am being mentally harassed. Plz help.
