Hi
I'm so sorry that this has happened. Very stressful for you.
I look at it this way. Relying upon one platform only for the entire livelihood is a recipe for disaster. You run on luck and one day that luck will run out. I'm 9 years hosting, and I'm sure one day, some stupid thing will happen and I'll end up not being able to take airbnb bookings.
So I have been slowly building up my website using the experience of what people have enjoyed and searched for to ensure its findable and bookable without airbnb. I'm no where near self sufficient but it's a start, better something than nothing. I also keep my options open on VRBO.
It's not perfect because the airbnb algo's and VRBO reward you for keeping all the bookings on one platform, not splitting but oh well. But you have properties that are much easier to book than mine and higher volume, so it shouldn't impact you so much.
So unfortunately no easy answer - you will have to go through the airbnb process. But there's nothing stopping you getting on other platforms quick smart and get those replacement bookings.
I also keep a copy of the bookings I do get separately in a spreadsheet (phone number at least) so if I am kicked off the platform, I can access the details and reach out directly to the guests.
Pardon for asking, and I'm sure other hosts are wondering, but I'm curious about the denying refund that kicked this off. I'm sure you had your reasons. But I'm scrambling to think of when I denied a refund. Infact, I'm the one normally volunteering it, because something has gone wrong. Was there very reasonable grounds to deny the refund, was it clear cut, did the guest admit wrong doing or was it shades of grey? When we are in business, sometimes it'snot worth the hassle and the potential unintended consequences as you have seen, to push back even if the refund denial was valid in your eyes. Just something to consider, albeit you didn't reveal the circumstance that led a guest to ask for a refund.
All the best, kind regs MK
