Lots of hosts here have experienced what you have. Take photos, get the repair co. invoice and submit a claim for payment through the resolution center. Do it right away, before the next guest's check-in time. Take a photo of the condition they left your place in. If you have a cleaner, have them give you a bill for the extra cleaning time and send it with your claim. Guest has 72 hours after check-i to claim the place is not OK and get a refund, so it sounds like 4 days is too long and you might have to tell the customer service person this, they are not very well educated on the Terms of Service, which seem to change frequently. Good luck!
