Spice Jet Airlines — Confirmed booking canceled

Address:

Ahmedabad, Gujarat, 380001

Booked round trip tickets from Ahmedabad to Pune & Pune to Ahmedabad on 23 june and returning 26 June.Week before got an sms from spice jet that tickets are canceled due to operational issues.Which is not at all acceptable.
We have planned everything hotel bookings and place to visit everything got booked.
Now they will refund money which is not all right saying sorry for inconvenience.
Who will bear charges for all cancellation.Booked tickets through yatra and spice jet people are saying we will refund money to them and you need to follow up with them for your money.
This is not a way, either going for cancellation they have to make another arrangements for the passengers who are traveling on that date.
I want spice jet to refund all expenses incurred on y traveling which is near about 20, 000.
