I want my refund:Booking ref 75178

My husband and i checked into Hotel Sky Cape Town on 23rd April and checked out on 24th April 2021-booking reference 75178.I booked though booking.com and made a payment via my Capitec Acc, upon checkout the payment was still not reflecting so i made another payment with promise from the Reservations Manager that i will be credited. I sent an e-mail on 4th May, phoned on 9th May and sent whatsapp to the Reservations Manager on 9 and 10th May only for her to inform me that the front desk manager will call me and i am still waiting for the call. This is horrible service because in essence i paid double the amount for just 1 night stay and now i must beg to be refunded. My advice to people is rather pay directly at the hotel to avoid all this drama.
