Jet Airways — unexplained charges

Address:	Mumbai City, Maharashtra, 400104
Website:	Jet airways e

I booked a flight to Delhi & back from the jet airways website after reading “free cancellation in 24 hrs” . I tried cancelling 20 days before the flight only to know I will be charged 90% cancellation fee. Which is exorbitant for making a simple mistake of planning a wrong trip. I would have paid if jet airways was incurring any genuine loss or administration. The policy is unexplained and there is no pain jet airways will actually go through by cancelling it 20 days in advance. As a consumer it is my right to know the break up this fee 18000 out of 20000? They are looting ppl for making a mistake, it is unfair !
