For that period i have worked 12-14 hours on daily wise without any leave. But when after waiting 4 month i did not get my salary, i get advised to leave the company by owner Mr. Hardas kucchadiya contact no- [protected], the return ticket was paid by company. when i Joined the organization my salary was decided 35000/- per month and i worked for 4 months hence the total workdone amount was Rs. 140000/- out of this amount i get only 20000/- hence my salary is balance around 1, 20, 000/-.
