Bharat Sanchar Nigam [BSNL] — non payment of rent by bsnl against the tower setup

The bsnl tower setup at p/o kantabanji - 767039, dist - bolangir, odisha. Despite various mails and letters to the concerned authority i havenot my rent from last 8 months by bsnl against the tower setup on my land. Further, the lease agreement period has been competed for about more than a year. Neither they are vacating the land nor they are paying rent. The agrrement is between kailash chand agrawal (Lessor) and the bsnl telecommunication (Lessee). I want the due rent to be paid as soon as possible as well as my land to be vacated.
