Booking.com give you a run around when it comes to refunds

I did an accommodation for Blue Waters Hotel Durban, through Booking.com for the 17 till the 19th. When I arrived to check in on the 17, I was told by the hotel that there is no parking, they only have 50 parkings. I had a rented car and I was told to park the car in the street and the hotel did not even provide a security guard for the cars, I refused because I know the area the hotel is in. its has lot of car break ins from addicts. I left and went and booked at Southern Sun next door. Blue Waters told me, only Booking.com can refund me as they were not going to take the money, as I showed up for the booking and was not happy. I am trying to get my refund, there is not contact details from booking.com and would like my deposit as the facility has no problem refunding me.
