sounds like you need to contact airbnb CS directly about this.
These boards have nothing at all to do with customer service - they are just used by other hosts such as yourself adn guests to share ideas, troubleshoot, offer support etc.
do you belong to a local FB group? Perhaps the moderator of that could also advise? Generally you are given the offer to bring a guest anyway when you book?
Hope it works out
