Booking.com Double Charged Me for Premier Classe Hotel

I am absolutely furious with Booking.com! On June 17, 2025, I attempted to book two separate double rooms at the Premier Classe Hotel Breda in Breda, Netherlands, through your app. The payment process froze and gave me an error, making me think it failed.

So, I tried to rebook. I couldn't find rooms with the same exact features, so I ended up booking one triple and one double room. To my horror, when I checked my emails afterward, I discovered that the original, frozen reservation had also gone through and been charged! I was now double-booked with extra rooms I didn't need.

I immediately called Booking.com customer service, explained everything, and they told me to talk to the hotel. When I called the hotel, they told me to talk to Booking.com customer service! Both parties are blatantly passing the buck, leaving me stuck. I used the first two-person, two-room reservation, but I paid for the extra rooms that I never used.

I demand an immediate correction and a full refund for the duplicate booking! All details and screenshots of the reservations are attached. Booking.com, rectify this error and return my money now!
