Shocked by Booking.com and Boutique Hotel OchSen, Bad Ragaz!

I booked accommodation on 21 November 2021 with a hotel in Switzerland (Hotel OchSen, Bad Ragaz). I cancelled within 4 minutes as I had made an error. The Hotel proceed to take the money off of my credit card. I pleaded with Booking.com for them to arrange for my monies to be refunded, but their response is for me to contact the Hotel directly for them to consent to the refund, which I did. The Hotel agreed to refund on condition that Booking.com condoned same. Booking.com did so. Despite reaching an amicable solution with the Hotel, no monies have been paid to date and no responses are provided to my e-mails and messages sent to both the Hotel and Booking.com. EXTREMELY DISAPPOINTED ALL ROUND!!
