Booking.Com

I made a booking with Booking.Com early this year. I booked the Capetonian Hotel,was informed the payment will be on the 1st August 2026. To my surprise I received an email from Booking.Com for a prepayment. Which I did as I was informed it's for an account validation. The payment was gonna be processed and immediately reversed. To this day I have not received a reversalon my account,I enquired at Booking.Com was told my card was declined. Contacted my bank,they told me the money was banked by Booking.Com on the 25/05/2026. When I told them that they say they do not have that money,I should do another payment. So that I can get an immediate reversal. I have sent Booking.Com emails but no one is responding.
