6 months ago, I started working in a customer service center for a US company who have outsourced their work to my employer in Pune. I worked there for 6 months and received a salary. I recently quit and my employer now refuses to pay me my last 2 months salary plus overtime charges.
The business my employer is running is not registered, hence there is no written proof of me having worked there. There are, however, ex employers who are willing to back me up and testify, if necessary. I also have email correspondence which will firmly establish my having worked there.
I would like to avoid any big expenditures, is it possible for me to send them a court summons or something that might coax them into paying me? I'm not really a wealthy person and I don't think I can hire a lawyer etc.
