Refund from Travel agency

Since two months I have not been able to get refund for cancelled Hotel booking,from No 1 travel agency in the country.I have sent a number of emails and talked on their Toll free number but there is no positive response.The amount is about Rs.10,000.00. Since I am out of the country, I cannot take up the matter in person except sending an email or talking on their Toll free #.What should be the next course of action
