@Norma412 Sorry you're getting no response from CS- you and thousands of others, it seems.
I'm not sure if you are aware, but the protocol to follow if you arrive to find a place unacceptable is to first notify the host, giving them an opportunity to correct the issue, then if the host is unwilling, or unable, you contact Airbnb, cancel and leave.
Did you communicate with the host about this upon your arrival? It obviously didn't get cleaned at all, and it's possible that the host assumed her cleaner showed up and readied the place for you, but simply didn't.
