Not giving a refund

I booked a JaguarXF for 5 days in Cape Town. When I arrived the car was not available (apparently the Jaquar XF has not been available in Cape Town for the last 2 months) and I was stuck in Cape Town at 22h00 without a car. Now that I want my refund of R 5,266.94 Budget Car Rental South Africa is blaming Travelstart South Africa and Travelstart South Africa is blaming CarTrawler who is not getting back to me. Apparently I also need to pay a cancellation fee of R1,000!!!!<br>
