Requesting for a refund.

Hi, I’m absolutely disappointed in Booking.com I made a booking this week for a one night stay at Royal Hotel in Durban. They debited the booking fee which was R572 but they did not send the confirmation number and the pin to me. I then proceeded to call them they said I have to go on the app and send an email to state that I haven’t received the confirmation number and pin which I did that, till today I haven’t received feedback, I ended up booking somewhere else, I tried contacting them to request for a refund and they’re calls are no longer going through.

Hello Peter please help me get my refund.
