Regarding non-payment of salary, if your gross monthly salary is not more than Rs.24000-00, you can file a claim u/s 15(1) of the Payment of Wages Act,1936 directly or through any Trade Union or the Inspector under the Act before the Authority who would normally the Deputy Labor Commissioner for the area where your establishment is situated.
Regarding your proposed resignation, the employer may try to adjust the unpaid salary towards notice pay. Even otherwise, you must serve the notice period if you can not pay the amount. In such a situation, the employer can not reject your resignation. My suggestion would be to get the unpaid salary first and only then submitting resignation. Alternatively, you submit your resignation with a Request to adjust the unpaid salary for two months towards notice salary and ask him to relieve you forth with.
