I was expecting a guest this evening ,he was booked for 2 days , He has just sent me a message via airbnb to say he cant make it and asking for an invoice for his job for monies paid . I have messaged him back saying i have not received any monies yet it is still with airbnb and he should contact them. he says he cant and that the money has been charged to his card .I have advised him to cancel so he will get something back as i have a flexible refund policy.is this all ok?
