Without undue delay get a legal notice drafted and sent to your HOD as well as the VC. If nothing transpires out of that then you must immediately approach Delhi High court either in person or through a lawyer. I never appeared before the high court of delhi but if you cannot find any other lawyer to file this case then I will take up your case and will try to seek relief for you from the Delhi High Court.
