MakeMyTrip.com — Wrong booking, description and photos

We booked a package trip with flight and hotel for 15.01.2015 to 17.01.2015 from Chennai to Hyderabad with a "good" but not to expensive hotel.
Booking mistake: flights where booked for 14.01.
No sorry, no excuse, no changing from their side, we had to change the booking with Indigo. After hours on the telephone they accepted to promise, they would refund the costs, from that day on no more message, no information, nothing.
Arrival at the hotel: the nice looking place, on their pictures nice looking, was smelly, dirty, bathroom was not cleaned for years, used bed sheets, nothing was like the pictures makemytrip was showing.
Again hours on the telephone, again no help, no excuse, not even a "sorry" on the telephone.
Again they promised to refund money, again we never heard anything from them, again no money arrived on our account.
