After 10 days of booking a 3-days stay through Hotel.com, the hotel customer service called me to inform that their hotel is fully booked and they have no idea how the website could sell the room. In order to clear the issue I tried to call the Hotels.com customer service if such a thing really exists. Hours of trying and zero result. The only service they provide after the booking is a chat-bot which brings all the unnecessary common topics just to check your ego-strength under pressure.
