I was working in a company and signed a bond on stamp paper for period of 3 years. The bond states that I can leave the company only in the month of june for which notice has to be given at least six month earlier. Also i need to pay the amount equal to twice the amount that i am supposed to get for my remaining tenure. As there is no proper exit from this bond hence i took leave from the company and never gone back to work. Now after one year since i left the company they have send me a notice on their letterhead that i have breached the contract and i need to pay around 12.5 lac rupees plus interest of 18% pa. I left the company after working 13 months (including 3 month of training). Moreover the bond is one sided in thier favour; they can terminate my job but i cant leave on my own will. If i do not respond to thier notice what kind of legal action can they take on me ?
