Dear Mr. Sumanta and all others who have similar ideas,
I agree with Vasant Nair and his well considered advice explaining the whole process. Don't try to fight your adversary. Your company would find it suitable to fight with you to establish a signal for others who wish to leave abrogating their part of the contract of employment. If one bird leaves, and is not shot in the mid-air, every other bird will leave the sanctury. What you have done is incorrect, both on moral grounds as well as on technical grounds. You can find your answer in your conscience. Look at the trouble you would put your company by not fulfilling the notice period. You just can't walk away and so many of us, criticize the company for their "hire & fire" policies, when we as employees fail to live up to some standards of ethics and moral values.
My suggestion would be that you meet the right HR guy (who can take the decision), talk to him politely and make amends for what you have done. Bravado will not do. If I were your employer, I would do the same thing that the company is doing it to you. Your reputation in the market would be destroyed if you wish to "see to its end". Take my advise - "patch up now"! Good luck.
