Never use Booking.com

I booked a hotel in the Gold Coast, Queensland using Booking.com. I had to cancel due to the death of my mother. I cancelled the booking online within the time limit and received a cancellation confirmation on line. Even though Booking.com charged me one night. I complained and they refused to refund my money. They referred me to a lawyers firm in Amsterdam that only accepts complains in writing over the mail. They never bother to reply to my complain. Never use Booking.com. They are dodgy
