Kesineni Travels — Kesineni Travels neither refunding money nor rebooking the tickets

I have booked tickets from hyderabad to bangalore at 10pm on 13th March 2015 with PNR: F66ETD in kesineni travels. Suddenly they cancelled the bus and informed via bus, once I called back didnt get any responce. So i have booked another tickets with Operator PNR # 6D1817 due to my emergency. After i called to Kesineni Helpdesk, reported the issue and they told like they wont return money and will give tickets whenever i requested tickets, now they are not responding i called 10 times per a day to them. Plese help how can escalate this issue
