A CONFIRMED BOOKING TURNED OUT TO BE OVERBOOKED

I booked accommodation at Ocean S****s in Bloubergrandt in Cape town. I paid for the booking on the 8th of June 2015, the reservation was confirmed on the same day and they sent me an e-mail saying that my booking is guaranteed and all paid for and they gave me a reservation number. I was surprised to get a call from [URL Removed] on the 14th of November 2015, that the property is overbooked and my booking has been cancelled. I am heartbroken and very disappointed. How will I get accommodation in Cape town I booked early for so that I would not be disappointed like this.
