Salary not paid for three months one month notice period

I had worked in a Bangalore based instrumentation firm in RT Nagar since Feb 2014 to December 2015 as General Manager Sales. As I did not receive salary for the month of October 2015, I submitted mail resignation requesting relieving and settlements. The Director came back to me with a mail terminating my services on Dec 2015, 24, and a table calculation of interests of investment on Stock accumulation during my services. I have clear appointment order mentioning salaries terms etc, which is general with not mentions of such clause. I would want labour consultant to take this forward
