Jet Airways — flight is cancelled, not providing the rescheduling now

Hi,
I have booked a return flight from del to vtz for 30th nov to 4th december, which is cancelled by jet airways now (Not disclosed the reason).
I have my further bookings dependent on this one, after managing them i will be able to travel on 14th to 18th december now.
But the customer care is not ready to give tickets on these dates as they are saying they can provide tickets within 10 days date range.
First, the flight is cancelled from your side, i am cancelling it, secondly this last minute change is costing me more now as i have to reschedule my full trip, so you need to understand that its not possible to have everything in your comfort zone.
If you cant provide me the tickets on given date range then reimburse me all the loss i will be having which includes the airfare, hotel reservation and further train tickets from vtz to tirupati. The total of which is about rs 48000.
