Employment bond breakage.

I signed for an employment bond in one of the popular construction firms. I'm a mechanical engineer from one of the IITs, but ended up working in this construction company.The bond was 2lakh amount for a period of 2years from the date of joining.But after I joined the company, I realized that the work profile is not according to their presentations during placements. I got totally fed up with my "work" ( on a night shift, I was just asked to monitor the number of trucks that took the soil from the dumpyard to the construction site, and their registration number and their timings!) .I read my bond agreement, again and was surprised to see that they haven't mentioned much About the work profile in the bond (Apparently I haven't noticed this while signing the bond). I quit my job after 13 months and just told my immediate supervisor and helped him for smooth transfer of my responsibilities. I informed the company after leaving, through an email that I'm resigning. Can they take any legal actions? They have been sending some notices to my home.I know from my past experience and friends that the Company doesn't really go behind this bond. But still I'd like to know what can be the worst scenario. Thanks!
