Reservation canceled last minute, couldn’t get refund!

Found a great looking sailboat to stay on in the keys. paid for 3 nights. did airfare and rental car and another night at a hotel in Miami. Got a reminder on Tuesday of this week that they are looking forward to our visit next week. Got an email last night that the owners canceled our reservation. No explanation, nothing. The email had a spot that we could click if we wanted to use the money that had been billed for another reservation. When we clicked it we were asked to find a site. When we did, it asked for credit card info. Nothing hinted at the fact that we were using monies already put on the card. The way the site is run I was not anxious to throw more money down a drain that so far I could not get it out of. The other button was for a full refund. I clicked it…..and was taken to a page that dealt with referring friends to AirBnB…are you kidding me?!?!?! Again…no sign that another button on this page would get me my money back. It was like me taking a toaster back to the company I bought it from because it did not work…the person at the desk asks me how many egg timers I would like…..What……I want to take something back that is broken…don’t ask me about buying more. Will NEVER use this airbnb crap again.
