I had a sort of similar negative experience with Airbnb
Host ended up leaving me a bad review. I replied to the review with with a message that had a URL which was stripped. I created a page with the full message history between me and the host (personal details blurred out) and wanted anyone reading the review to come to their own conclusion.
Tried contacting support, tried contacting the "higher ups". Got no where. First and last time I used Airbnb. Cancelled my account shortly after.
Honestly it seems pretty clear they want all reviews to be on their platform (not just you but also the OP). There's a lot of things to dislike about Airbnb but wanting reviews to be inside their platform is pretty reasonable (prevents doxxing, fraud, harassment etc).
