CANCELLATION OF BOOKING - UMHLANGA SANDS

I'm extremely disappointed with Booking.com for cancelling a booking that I made with them for accommodation at Umhlanga Sands self- catering units. Initially, I was sent confirmation via e-mail, with a booking reference number. Today, I received a call from a consultant, informing me that the accommodation was no longer available. Preparations were already under way for this weekend treat, and left many people disappointed.
