Breach of rental contract during lock-in period

Dear Sir, Hello I have a commercial property in Pune which was duly rented to a Foreign (korean Company) for a period of 2 yrs as Lock-In period on which he even registered new company through Registrar of Companies during this process, I supported him by all documents, Utility Bills etc but to my surprise I receieved a notice 20 days back that he is going to vacate after 2 months time wherin they have not even completed the one year as tenant. Further he has not even paid the TDS which was deducted from the rent. Kindly advise as I have 2 months deposit for which they have stopped paying me. Appreciate an early and favourable response to compensate my losses due to breach of rental contract. Best Regards Dr Ali kaliimran@gmail.com
