Booking.com — sold a room in this hotel booking. con

I have worked so hard and rob me of my money eg cant get my 487 Euros back
I have booked a room from 512018 to 1212018 when I booked it said I cant get my money back I took it for granted that the hotel would be clean have no cockroaches or rats or the building falling apart when I looked up trip adviser it had photos of all of the above the hotel in question is Hotel Pennsylvania 4017 Avenue Chelsea New York I really feel sick now how can they sell booking in this place
Booking.com were no use saying they were sorry joke.
Now I find out this week they are warning people to not use showers or brush teeth teeth fore fear of contacting Legionaires disease,
