Hi, I joined a company on 13 SEP 2018 in Pune as a R & D Engineer with a bond of 2 years, it was not on stamp paper it was just a normal paper. I was assigned for duties which was mentioned on the joining letter, but later when I joined the company everything was different they shifted me to different department , no R & D work I was in different department, now there are many reasons by which I left that company after 1.3 yrs ( one of the reason was they didn't have salary for two months) as I got better offer, but now they are holding my last month salary they are saying " there was a bond and we are deducting it from your salary". can I file a case against them.
