Booking.com / Bungalowpark Domaine De Chodes In Belgium — this is a scam!

My complaint is because booking.com works with a hotel by the name of Bungalowpark Domaine de Chodes in Belgium, which apart from being of awful quality, also rips off their customers. In the confirmation they sent me they said that the credit card was only for reservation, and that they wouldn't apply payment. Then they asked for a wire transfer. I sent the wire transfer, and immediately after they charged my credit card. In that sense they charged me twice. During my unfortunate stay at the hotel I tried to get reimbursement and they gave me the runaround, it is 6 months later, and now they tell me that the rate was wrong... Clearly this is a fraud. My complaint is that booking.com should make a more thorough due diligence of the hotels they provide access to on their site. In this case I was robbed. Will never use booking.com again, and recommend that people be aware that the quality of the hotels they provide in very questionable.
