@Lucas732 I see 2 reviews on your profile, both from back in 2019. In one of the reviews you left for the host, you had also a raft of complaints, and the other, you said "not as pictured" and that listing has a ton of terrible reviews saying it was filthy, among other complaints.
I'm getting the impression you book the cheapest places you can find, and then complain because they aren't nice.
You can't just continue to stay somewhere you find unacceptable and then expect to get a refund. "Too busy" isn't an acceptable excuse for not following the clear protocol for cancelling and leaving right away if you feel you should be refunded.
I don't know why your review wasn't posted, unless it violated Airbnb review policy, but I can tell you that reviews aren't posted in chronological order, so if the host has tons of reviews, yours could be there many pages back.
And I would advise you to pay a little more money for nicer places, don't book places with bad reviews, and stop booking places, staying, thinking you should get a refund, i.e. a free stay, and then trashing them in the review.
No host wants a guest who behaves like this.
