Paid Holiday accommodation cancelled last minute

I signed a contract for Holiday accommodation through Harcourts Hartenbos on the 10th June 2015, however I only received the signed copy back from the agency on the 20th July 2015 after numerous requests. The booking was made from the 19th December 2015 - 4th January 2016.<br> Payments towards this contract was made as follows:<br> Amount due as per contract: R22 510.00<br> Deposit paid: R16 000<br> Balance of R6 510.00 woud have been paid beginning December before occupation.<br> However, I received a Whatsapp from the rental agent this morning advising me that my accommodation is no longer available and that I will receive an email with an alternative option.<br> The option offered to me is not even close to being similar to what I had already booked and paid for.<br> I freaked out this morning seeing that my accommodation was booked for less than a month from now, and Hartenbos being such a popular holiday destination, it is basically impossible to get accommodation at short notice.<br> Since the last payment was made and a fully signed contract received which clearly was not actioned or followed through - nothing has happened from their side.
