Double Booking

Good morning, We booked for accommodation in March for 8 people through Booking.com at Gateway on Kruger in Marloth Park and we paid the full amount in October. We had booked from the 4th to the 7th of November, we drove all the way from Pretoria to a fully occupied Villa. The people we got in the Villa had checked in on the 2nd of November and Checked out this morning. We were rained on and we got assistance from the Manager of Marloth Park, they booked for us at a place which is totally different from what we booked and the Gateway on Kruger office didn't even bother to help us with anything. We're told now that we need to check out at 10am or pay for today or head to Gateway on kruger to pay R3000 for the day on top of the R9000 we had already paid.

The saddest thing is that, the family that occupied the villa paid a lot of money than us and got 5 star treatment, just because we're black we don't deserve the same treatment..and that our money was too little. How does a company not take note of a double booking? Where are we supposed to go cause our transport is public and is scheduled for tomorrow morning. We got an email from booking.com, asking us not to take this any further, but we're now frustrated, cause we have nowhere to go.
