This booking.com is a scam. They will charge your credit card for full amount of hotel stays whether you stay or not. No cancellations or modifications on your booking. It is run by a bunch of foreigners. Do not expect any refunds or help. When you make a reservation that's the last you ever get in touch with them. They no longer have any contact with the hotel you made the reservation with. I have contacted a lawyer and my bank to try to resolve this problem. I would advise anyone else that has problems to do the same. Better business bureau should truly do something about these companies.
