@Ruth924 Customer support is extremely slow these days for everyone, but you do get better results if you actually know the policies and follow the protocol. The Guest Refund Policy is here: https://www.airbnb.com/help/article/544
If you found the property dirty upon arrival and decided to cancel the booking, you should be eligible for a refund. But if you completed your stay, there is no reason to think you're due anything here. Nowhere in that policy does it say the Cleaning Fee is refundable if you find the cleaning insufficient.
