After making a reservation with booking.com I found the exact same room and options (breafast included etc) at a cheaper price directly with the hotel. I tried to use their price match offer and included links to the room and a screen shot of the price. For an unknown reason the claim was rejected. I spent 2 days on a chat just to get them to send the link to make a claim which they took a week to reject. In my opinion it's a scam, I would use another booking website. I will not use booking.com again. Inflated prices, useless customer service and they passed the wrong details onto the hotel (which i corrected myself rather than going through the hassle of trying to contact them again).
