How to get back my house rented house deposit?

I used to stay in a rented flat in Bangalore till August last year. The house owner refunded to me only Rs 75K out of our deposit of 95K and that too after a delay of 7 months. The house owner wrote to us he will return the rest 20K, but lately has not been replying to my emails at all.
