[Resolved]  Landlord Harassment — Harassed by landlord

I have been living in a rented flat for the last 1 year. Now, in the previous month i have decided to terminate my agreement as I am getting company accommodation to live in. For the accommodation where I am now living, i am paying a heavy rent and I have given more than 5lacs refundable security deposit, which has been financed by the bank I am working. I have an agreement between me and my landlord that at the end of the term of the lease, he would pay me back the amount of more than 5 lacs to me, and I would return it back to the bank where I am working. But after termination of the lease, my landlord doesn't seem to give us any guarantee of the security deposit, on the contrary he is threatening us that he can write off the full deposit, if we ask for it several times. We just wanted an affirmation that he would pay us back by the date of the termination of lease, which he doesn't intend to give. What sort of action can we take against this person. To make matters worse, the accommodation that I would get from my company might be scrapped if I do not return back the money. please help!!!!!
