refusing to allow a booking change

Today, 14 December. My wife made a booking at a BNB for the holidays but upon arrival an inspection of the property reveled a broken bed, no hot water, leaking gas stove and less than helpful management. as it was after 7pm many places already most probably had been booked, we looked around the airbnb site for alternate accommodation but due to the systems set up at this site i was not able to make contact directly with a bnb close by. When trying to get contact details to confirm if they had place for a large group of people and a elderly couple, urgently airbnb kept blocking my info and not allowing me to contact any other bnb's in the area possibly due to the fact that i had already made a booking. i am giving the management of airbnb 12 hours to respond to this issue or i am reversing the payment and laying a charge of ***** at the local sap as non of these problems were mentioned at their site. We are now being held ransom at what is basically a prison with mild gas chamber.
