Notice period in pvt.ltd company

Hello all, Good Evening! Before a month our company has shutdown our process and out sourced it due to the cost efficiency reasons and we were forced to relive from the organisation immediately but they haven't provide us with the Two month salary as a compensation. When I enquired regarding this to our organisation, I didn't get any proper response from them and later they have provided me only 15 days salary. Also it has been mentioned in the annexure that the paper time for our company is 2 months and if we wish to relive earlier, we have to pay for the number of days that we cannot work so I hope likewise the management has to pay us with 2 months salary, since they closing the process immediately. In this case, I would like to know whether the policy of providing the employee with 2 months salary is in the employee act or not! and If it is in the act how should I proceed further? Really thank you for taking your time to read my email, looking forward to hear from you soon!
