Cleartrip — issue

My flight tickets from clear trip was cancelled and they didn't notified me until i call them to check the flight time on the same day, they told me to purchase a new tickets and will refund the amount within 7 days, now its 30 days and didn't received the refund amount for rs.54, 000. Now when i tried to call they and they are saying it will take 45 days from now. I believe this kind of company they should me shut down.
