Poor service - refund for non stay. Hotel got booked directly due to non confirmation from booking.com

Hi there

I made a reservation on booking.com. I have received no confirmation email, which includes the pin you need to confirm your booking. Ref number was given to me over the phone: ***. The Cullinan hotel in CT confirmed that they have not received my booking via booking.com, therefore they reserved a room for me. I paid the hotel on the 27th of November for the stay of the night of the 27th of November. My credit card still got charged with booking for a room by booking.com and there is no way that the app to resolve the double charge on my card. Raizia from the hotel mailed booking.com customer service with no reply, I phoned both the TOLL FREE AND THE Uk numbers provided by customer service on google. No support whatsoever. Between the Cullinan hotel and booking.com 2 charges were deducted from my card. I wish for booking.com the reverse the $ 290.15 from my card. The drop down menus for customer service do not include an option to get this matter sorted and there is no option for free text. Truly unacceptable service. non- existent to be honest. I honestly hope that someone will call / email me to get his sorted. my mobile ***. thank you Dr Christien Groothof
