Bookings.com continues deductions off my card

I have an issue with Bookings.com I made a booking at the Royal Palm Hotel in Durban via Bookings.com beginning of October. I paid for the booking using my card. The money went off and out of my account. Law and behold, 3 weeks later two more charges have gone out of my account and I am still waiting for a Relationship Manager handling the Royal Palm Hotel Umhlanga to call and also refund me. What an inconvenience by both Bookings.com as well as Royal Palm Hotel.
