Air Deccan
Refund not recieved

I have booked a round trip to bangalore from delhi (ticket number 6777573). I have also requested the cancellation of this ticket as there is a change in my schedule. Despite of recieving a reference number against the cancellation, I have still not recieved the refund. whenever I contact the customer care centre, they assure me that it will be done in a week's time, but I am fed up of their false assurances. My reference number for cancellation request is 132880. Kindly take a note of this matter and roll back my refund at the earliest.
