Ivory lodge is racist

We arrived at the lodge on the 30 /4/2019 and we checked inn at the reception and we were told that we need to hurry up and leave our bags in the room as it was time to go for the dusk game drive, which we did. We came back to the reception and the drive was delayed by almost an hour because the lodge had Brazilian group (visitors)who needed to re-group for a quick meeting and we waited. When they were done with the meeting they started getting onto the cars and I also got on the car, but I was told get off from the car ,and allow the group to get on first, which I did. The group got on first and we waited for them and the cars started leaving without us ,including the car that we were allocated to for the ride and 4 of the cars has space for 2 or 1 person/s, including the one that we were allocated . I went to the reception to ask what happened no one could explain why were left behind ,despite the fact that there was a lot of space available. I was promised a refund in 7 days, when I phoned and emailed on the 2 May , my email was not responded and no one seem to know exactly when I will be getting my refund. We were told not to get on the cars , because everyone was white and the 2 of us are black individuals
