So I booked two rooms in Booking.com and it said that there was free cancellation, so I was confident it reserving it, since I wasn't quite sure about booking the rooms but I wanted to reserve them anyways, so having free cancellation was really convenient. I reserved the rooms using an online debit card with barely any money, since I haven't got the money yet for the rooms.
The people I was supposed to stay with then bailed out so I cancelled the booking but it said it would charge me the cost of the two rooms. It clearly said free cancellation so Im confused as to why I'm going to be charged. I booked a new room that I would stay in instead.
My question is, why am I going to be charged for the cancellation and how will the hotel charge my empty online debit card?
Also, since I booked a new room, I'm planning to change my bank details on my new booking and put in a credit card. Would the hotel charge the new credit card for the old two rooms or still my empty debit card?
Also, is it still possible to retrieve my first reservation of two rooms and just sell it to others?
