Three weeks ago I did a reservation booking and immediately received a message from the "host" to pay for the room within the next 12 hours with a link leading to a booking.com clone website asking card details. It look really legit, except one strange message: "If you don't remember the sum to pay, just enter 350€". Even Google chrome detected this as scam and shown the red warning screen about the site being a phishing danger.
I've reported this issue to customer support (cloned site, screenshots) and their answer was "If you are not comfortable about entering your card details you can try to contact the property directly using their phone number". I wonder how it could have helped?
Lucky I could cancel the reservation without any penalty and I'm really thinking not to use booking in the future. They take the commission but can't even make a simple check about a property which is obviously a scam ...
Very unprofessional.
