Nothing

I just arrived in Abuja, and when i called this property, the owner on the phone said that, my booking is not available. The room that i booked is not available, Yesterday night when we spoke, he said his cheapest room is 15000 naira, and today he's telling me the room available is 20000 naira. While we talked yersterday night after i booked on booking.com. This is unhuman because i came with my family, And it was already very late (23h) luckily i took an uber and the driver helped me to find another hotel I can never advice people to use this hotel. But i think it's because i'm black, because If i was a white man he should've treated me differently. What a bad experience!!!
