An inquiry can not be convered directly by the host into a confirmed booking (Inquiry: you need to use "contact the host" link on the listing, and wait for a pre-approve of the host. After that you can decide if you want to book or not.).
So you probably made a booking request, which is not the same as an inquiry, and can be confrmed (automatically or manually) by the host.
Some listings have possibility to cancel within 48 hours and have full refund.
Maybe check the listing(s) for this

This is the community, we have no access to your details, please contact Airbnb or the host.
