Airbnb Inc. and Floridafuntourism.com Florida Fun Airbnb Predatory greedy Airbnb host Airbnb Inc. takes no accountability for facilitating Kissimmee Florida

I booked a stay listed on airbnb from their host “Florida fun” aka floridafuntourism..com. Within 24 hours I learned the family member that I was planning to visit in Florida had been diagnosed with a thyroid tumor and would be having to undergo treatment instead of seeing us in their hometown of Kissimmee. I immediately contacted the host and told them of the news. They refused a refund and asked for proof. I sent them images of the text conversation. They denied my claim with no words or anything just denied and kept the money for my stay saying they have a no refund policy. I was out $837 for a service not completed! I contacted Airbnb support  and they denied a chargeback. They said the seller had a no refunds policy so there's nothing that they can do. I believe that Airbnb is facilitating unethical business. I want to note that it would have been easy to book this by mistake as there is no slide to reserve button that most use to protect buyers on their site. The host Floridafuntourism.comhas the property relisted on the same date and will likely have it rebooked. I don’t see how they lost any money but I do see how they are preying on customers for extra profit! Both Airbnb inc and Floridatourism.com are actively looking for every way that they can profit even if it is at the loss of others. No service was provided but I still am paying for the stay. I will try to chargeback through my card but I believe both of these companies need to be investigated.
