Musafir — Flight booking cheating

Address:	Mumbai City, Maharashtra, 400069
Website:	Musafir.com

I had booked domestic flight from musafir and made the payment after which they accepted the payment and later they just cancelled my booking for the reason price of the service had gone up after 10 mins and sold all the seats now they asking me to pay double amount or take the refund after 10-15 days
What the hell is this??
I had made the payment and the amount they had asked for, the exact amount not even a single rupee i had shorten the whole amount i had paid even after that cancelled my booking
This a fraud cheating done to me
Plz make sure anyone doesn't gets cheated next time for which i am making a complaint
