Instant Booking HELP

[Karl-and-Cindy0]

Hi everyone, I’m not sure what to do… I’m a month and a half in. I didn’t know anything about IB and all of a sudden I got two IB’s.  

the short story is we lost our furnace, won’t be replaced until the 9th. We have a heater but it’s loud.  

I've emailed the person, who is booked for the 2nd,  twice and told them the situation and asked for confirmation that they’re ok with this. I haven’t heard back. This person has no reviews, no profile, no picture and joined in 2016, and 6 people for two nights.  

I’ve read in Airbnb help section that it is ok to cancel a person that you feel sketchy about with no penalty.  However, I’m still losing a booking.   What should I do?  I’m at a loss. 

Thank you, Cindy
