Hi @Tracey58 When he requested the addition day, the best way to do it would have been to go to his reservation, then click "Change or cancel", make the changes and then submit. He would have had to accept the change to extend his stay. The only thing you can do at this point is to escalate your Resolution Center request to Airbnb & get them involved. There is an option for that in the Resolution Centre request you have started for this guest. Hope that helps & best of luck getting that sorted! Karen
