What happened with you has already happened. But you are trying at wrong places. Why would an air India babu bother to get another one of the same clan caught. Do one thing, there is a vigilance officer contact on airindia website. Put your story there and see the effect. That vigilance officer is not from Air India. He happens to be a Govt of India representative with nothing to do with AI. When vigilance squeezes this azzhole, at least others will benefit from your case.
