I have been employed in a company for the past 8 months in IT. I signed the appointment letter and offer letter, which were in the custody of the employer. However, I haven't received my copy of the same. I have now decided to quit my job citing personal problems, but my employer sent me a legal notice, forcing me to work the notice period of 3 months or threatening to sue me for data theft. What should I do? Note: there isn't a buyout option available as well.
