respected sir,

A company cannot force you to fulfill the notice period. The employment agreement usually has the clause that states 90 days written notice or 3 months' gross salary. you can issue a written notice to the management by communicating about further development and requesting your relieving letter. you  can also approach the labour court or the tribunal by issuing lawyer notice to the Management, HR and Reporting Manager. Further you may also consider moving the High Court under Article 226 read with Article 14.
