Bad service

I booked a room for a whole month and when I went to the place I found that it was not in a liveable condition, I then sent a complaint to AirBnB and the customer service person was extremely rude, he refused to listen to my complaint and only listened to the host, I then did some work on my own and found that the host was not the owner of the premise and she was leasing it from another person, I contacted the owner to find out if the host had permission to sub-lease the place and the owner said it was not in the lease agreement. I then called AirBnB to inform them of what happened and have not received any response from them, the service is extremely appalling, they favour the host and you as the person using their service have no right to anything.
