I have served a 3-month notice, which is the norm in my company. They didn't accept my resignation, citing some lapses, to which I dutifully replied. After the 3 months, I waited another 4 1/2 months beyond my initial notice period. Even then, I did not receive any response or acknowledgment. As it was high time, I sent an email stating that I would not be coming to the office from a certain date. My company now tells me that they will take disciplinary action against me as they want me to continue working. I have not attended since then. My PF and gratuity are due to me. What do I do? Please guide me.
